Virtualization Context Connection

A cloud virtual server differs from a regular VPS in the presence of an installed Virtualization Context daemon (service), which automates server configuration and allows you to add/remove IP addresses or increase disk size, as well as other parameters without rebooting.

By default, all virtual servers deployed in the Cloud VPS service context work with the Virtualization Context daemon installed and running.

If the server does not have this package, you can install it manually. For this:

Configuration should be done in the ONEVDC cloud server control panel https://onevdc.net

1. Choose the virtual machine in the VMs section

setup-virtualization-context.4

2. Stop the virtual machine

setup-virtualization-context.6

3. Go to the Storage tab and click the Attach disk button

setup-virtualization-context.8

4. Select the Contextualization Packages disk

setup-virtualization-context.10

5. Run a virtual machine

setup-virtualization-context.12

Then look at how the virtual CDROM was connected, in this case, it is the /dev/sr1 block device.

[root@test123 ~]# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0     11:0    1  364K  0 rom
sr1     11:1    1  990K  0 rom
vda    252:0    0   15G  0 disk
└─vda1 252:1    0   15G  0 part /
Copy

6. Mount the CD drive to a folder, for example /mnt

[root@test123 ~]# mount /dev/sr1 /mnt/
mount: /mnt: WARNING: device write-protected, mounted read-only.
[root@test123 ~]# cd /mnt/
[root@test123 mnt]# ls -l
