You can add capacities (for example processor cores) to your created cloud virtual machine. Learn more about how to create instances here.

In order to add vCPUs, go to the PROJECTCOMPUTEINSTANCES section and select RESIZE INSTANCE from the drop-down menu in the instance chosen.


In the window that opens, you will see all available resources (the OLD FLAVOR item). In the NEW FLAVOR item, select the instance type with the required number of vCPU cores.


The next step is to confirm the instance type changing.

Подтвердить изменение типа инстанса

In the same way, if desired, you can reduce the number of processor cores, if there is no need for large capacities.

You can only access your cloud instance from an external network if you have associated with it an external IP address (Floating IP).

These addresses are not allocated automatically. The external IP address of your VM must be associated with the internal one.

To assign an external IP address to your instance, go to the PROJECTCOMPUTEINSTANCES section and select ASSOCIATE FLOATING IP from the drop-down menu next to the instance name.


In the window that opens, click «+» under IP ADDRESS.

Floating IP Assignment Management

In the next window, click ALLOCATE IP, and then you will be immediately re-directed to the previous page.

Allocate external IP

An available white IP will appear in the IP ADDRESS drop-down list, which you can allocate to the port of your VM. To complete the setup, click ASSOCIATE.

Floating IP Assignment Management

Sometimes you may need to allocate an external IP address to the instance's network interface without using SNAT. To do this, you can rent a subnet from us.

Attention! When renting a subnet, three addresses will be used for service purposes: the network address, the default gateway, and the broadcast address. If you use DHCP, 2 more addresses will be used for DHCP agents (primary and backup).

The cost of the subnet for rental resources in Europe:

Subnet Number of IP addresses in the subnet IP for a VM without DHCP IP for VM with DHCP Cost, Euro
/30 4 1 0 8
/29 8 5 3 16
/28 16 13 11 32
/27 32 29 27 64

1. How To Configure The Network

After you have received the access details for your project and have logged in to it, you should first configure the network where your instances will work. To do this, go to the PROJECTNETWORKNETWORKS section. To start the network creation process, click the CREATE NETWORK on the page that opens.


In the NETWORK tab, you can enter any name in the NETWORK NAME field. In our example, this will be my_net_1.

Attention! To avoid any errors, all names should be written in Latin letters.

Create network

Next, you should add a subnet for your network. Enter any name in the SUBNET NAME field on the SUBNET tab. We recommend setting different names for the network and subnet — for example, my_subnet_1

Below, in the NETWORK ADDRESS field, specify the address for the subnet to be created, for example: You can leave the GATEWAY IP field empty — in this case, the first address of the selected network will be used by default. Alternatively, you can provide a specific gateway IP address.

Create network

Please make sure that all data is correct, then open the SUBNET DETAILS tab. Check the ENABLE DHCP box. In the ALLOCATION POOLS field, enter the start and end values of the issued addresses separated by commas without spaces — for example,, You can use our addresses as DNS servers, or any other. Addresses should be written as one per line.

Our DNS addresses for Europe:

Create network

Then click CREATE, and the created network will appear in the list of networks.

You should create and configure a router to ensure the operability of the network you created. Click CREATE ROUTER in the PROJECTNETWORKROUTERS section.


In the opened router creation window enter the router name (in Latin letters!) - for example, my_router_1. In the ADMIN STATE field, select UP, and in the EXTERNAL NETWORK field, select admin_floating_net, and then click CREATE ROUTER.


The router will appear in the list. To continue configuration, click on router name.


On the page that opens, select the INTERFACES tab, then ADD INTERFACE.


In the SUBNET field, select the previously created network and, if necessary, specify the IP address from the created range, then click SUBMIT.


This completes the network setup. Now you can create your first VM and configure security rules for it.

2. How To Create An Instance

Before creating an instance, it is first recommended to check the available resources that you can use in your project. To do this, open the COMPUTEOVERVIEW section. On the page that opens, you will see a LIMIT SUMMARY of your resources.


You can find all the VMs you created in the COMPUTEINSTANCES section. To create an instance, open the COMPUTEIMAGES section, then select the PUBLIC tab. Here you will see a list of all available images for creating VMs. Once you have decided on the desired image for the instance, click LAUNCH next to the device name. In our example, we used the image of a Debian 10.


In the instance creation window that opens, enter the desired VM name in the INSTANCE NAME field, which will also be used as the hostname, for example, Debian_test. You can increase the number of created instances in the COUNT field — in this case, they will be allocated to the corresponding indexes.

Launch an instance

In the SOURCE menu item (on the left), select CREATE NEW VOLUME and set the volume size. You may also change the image that the VM will be created from, if required.

Launch an instance

In the FLAVOR menu item, please select a template based on which resources will be issued for the VM. If a template exceeds the resources available to you, an exclamation mark will appear next to it. To select a template, click + next to it.

Launch an instance

If you are creating an instance based on a Linux image, you should create a key pair in the KEY PAIR menu section on the left. Without this, you won't be able to connect to the created VM via SSH. You can import an existing key pair using the IMPORT KEY PAIR. If you want to create a new key pair, click on the CREATE KEY PAIR and enter the name in Latin letters (for example, debiankey2). Once created, the key file will be downloaded automatically by your browser.

Launch an instance

Linux/Unix only: if you plan to connect to the VM via the console and you do not need SSH access, you can add the following script to the CUSTOMIZATION SCRIPT field in the CONFIGURATION section:


password: userpassword

chpasswd: { expire: False }

ssh_pwauth: True

where USERPASSWORD is your connection password.

Launch an instance

After you have finished making changes, click LAUNCH INSTANCE. Your VM will appear in the list of instances, and after a while its status will change to ACTIVE. The next step is to associate a white IP address with your instance. To do this, select ASSOCIATE FLOATING IP from the drop-down menu next to the name of your instance.


In the window that opens, click «+» under IP ADDRESS.


In the window that opens, click ALLOCATE IP, and then you will be redirected to the previous page, where an available white IP will appear in the IP ADDRESS drop-down list, which you can associate with the port of your instance. Click ASSOCIATE to complete the configuration.

The user name for Linux instances is the same as the distribution name: DEBIAN for all versions of Debian, FEDORA for Fedora, etc.

If your VM is Windows-based, open the COMPUTEINSTANCES section and click the name of the corresponding instance. On the page that opens, go to the CONSOLE tab and configure the system.


Your cloud VM is now successfully created, but you still don't have access to it via SSH or RDP. To connect to an instance, you should make changes to the current security group.

3. How To Manage Security Groups

To change security group rules — create new ones and edit existing ones — open the COMPUTEACCESS & SECURITY section.

Click MANAGE RULES next to the DEFAULT rule.


On the page that opens, select ADD RULE.


In the window that opens, select the required parameter from the RULE drop-down list: SSH for Linux or RDP for Windows.

Attention! You should only change the other fields if you are absolutely sure that these actions are necessary.

Then click ADD and the rule will be saved.


You can create separate security groups for different VMs. You can do this directly during the instance creation process from the corresponding menu section. You may also change the security group for existing instances in the COMPUTEINSTANCES section. To do this, select EDIT SECURITY GROUPS in the drop-down list next to the desired machine.


You are now able to easily connect to the VM you created via SSH or RDP.

If you rent or host several servers within our data center, you can combine them into a single closed network based on Private VLAN (PVLAN) technology.

Two servers can be directly connected using an Ethernet cable. This service is provided free of charge.

If you have more than two servers that need to be combined, you will need switches with the configuration of separate VLAN. This service is paid. The current cost of connecting a Private VLAN is provided on the RENT A SERVER and HOST A SERVER pages in the ADDITIONAL SERVICES section.

Please note that a Private VLAN can be set up on either a 100 Mbit/s port or a 1 Gbit/s port.

By default, each server has two network ports: LAN-0 and LAN-1. One port is normally used for Internet access, whilst the second can be configured with a Private VLAN. However, we can install additional network cards, for example to aggregate ports into LACP trunks.

For your high-load projects (cluster systems, disk arrays, etc.), we can offer you optical switches with ports of up to 10 Gbit/s, on individual terms.

Our specialists will set up the Private VLAN within one day. Please contact our technical support to order a service.

If your browser fails to load a website showing the following message:

Your connection to this server has been blocked in this server's firewall.

You need to contact the server owner for further information.

Your blocked IP address is XXX.XXX.XXX.XXX

This server's hostname is YYY.YYY.YYY.YYY

where XXX.XXX.XXX.XXX is your IP-address, then we request that you copy the message and send it to our technical support. You may also only specify the IP address mentioned in the message and the address of your website (your domain). We will find the exact reason why your IP address is blocked and unblock it.

Attention! Showing this message does not mean that the actual website is blocked, but that the specific IP address from which you are trying to access the website has been blocked, for some reason. The website can still be accessed from other IP addresses.

When working with the IPMI View program, while connecting to the server console, you may encounter the CONNECTION FAILED error. To restore the server's connection, follow these steps:

  1. Exit the IPMI View.
  2. Log in to the web interface of the IPMI controller using the same details (please note that the IPMI web address and your authorization data are available in your Personal account and in the email that we sent to you when granting access to the server).
  3. Go to the MAINTENANCE tab.
  4. In the left-hand side menu, select IKVM RESET and click RESET in the window that opens.
  5. Exit the web interface.
  6. Start the IPMI View and try to connect to the server again.

Attention! These actions will not restart the server itself, only the IPMI controller.

The current version of the IPMI View is available here.

When working with a remote access PuTTY client in Windows, an error may occur due to incompatibility of key formats:

Unable to use key file (OpenSSH SSH-2 private key (old PEM format))

To eliminate this error, the key must be converted by the PuTTYgen tool. Download the utility through the website, open it, and select the "Conversions" tab in the top panel. In the menu that opens, press "Import key" and select the key.

Import key

To convert Keys after import, click "Save private key." The key will be saved in a new format (.ppk) with the selected name. If necessary, you can also set the password for the key.

After that, you can connect with a new key to your servers or virtual machines in our data center.

Every dedicated server you ordered includes unlimited KVM access (KVM stands for Keyboard, Video, and Mouse, also it can be named KVM over IP — a virtual remote console for your server). Using this you can work with BIOS and OS directly without our tech support.

For all standard dedicated server plans KVM Virtual Media feature is available. It allows you to upload to the server any files — it’s usually used for ISO images for OS installation. You can then mount it via virtual DVD-ROM.

You can also power cycle your server via KVM web-interface, IPMIview app, or My account.

You can always add authorized users to Your account. Those users would be able to manage services and payments as well as send support requests via tickets and webchat.
