thank you, will read about Openshift, I don't know what is it, with docker I was always use Portainer

Thank you, @f33dm3bits Security patches is big trouble, but I will always ignore it to avoid reboot. At common I'm solutions architect of this system and of course administrator of all servers of this solution. And I see a lot of advantage and disadvantage of both main way - docker inside KVM...

I have installed KVM with 30 Ubuntu (in future will be more) on Ubuntu and finally that bunch of VM working fine. But my next test in this server is adding to this machine huge amount of docker images - more than 50. And I thinking, but no answer what is right way to do this. First way is place...

No, sorry. I decide erase this server at all and now I waiting result of # dd if=/dev/zero of=/dev/sda and # dd if=/dev/zero of=/dev/sdb 118751232000 bytes (119 GB, 111 GiB) copied, 281.246 s, 422 MB/s if issue will be repeated in next generation of this system I will continue this topic

this is all we know about cloud providers, their installation script set up OS to one disk, than boot system from another disk

Ups, I have undertand this issue! server booting from /dev/sda but my system setting into /dev/sdb and /dev/sda has old grub from Ubuntu 16.04 # cat /etc/fstab proc /proc proc defaults 0 0 # /dev/sda1 UUID=e9774f22-de84-45a3-847c-a2ae6b347676 /boot ext3 defaults 0 0 # /dev/sda2 belongs to LVM...

Thank you @f33dm3bits , this is my grub.cfg setting by cloud provider

I install Ubuntu 20.10 in cloud provider and receive # uname -r 4.15.0-60-generic # ls -ls /boot total 147484 248 -rw-r--r-- 1 root root 248258 Jan 18 17:01 config-5.8.0-41-generic 248 -rw-r--r-- 1 root root 248258 Feb 5 03:41 config-5.8.0-43-generic 4 drwxr-xr-x 4 root root...

Ups... cloud provider set wrong interface name !

Thank, you @f33dm3bits , now I try another way, I fully destroy server and try to go to Ubuntu 20.10 - my expectations is new version of KVM in Ubuntu 20.10, but of course if issue will repeated I change partition type to dos. Thank you.

Hello, I have issue with network in Ubuntu 20.10, this is cloud service and I can not select packages during installation. Cloud service prepare for me 01-netcfg.yaml file for networking with my IP addr and that it. nmcli is absent, networkd daemon not working, ntewotk-manager missing...

I want to summarize this topic andmy issue. I have googled about half of day similar issues and found about 70.000 pages with description similar to https://serverfault.com/questions/407842/incredibly-low-kvm-disk-performance-qcow2-disk-files-virtio - for that gay disk with speed 120 mb/c KVM...

this is attempt without XML at all # virsh vol-create-as dsk-b sdb1 16G error: Failed to create vol sdb1 error: internal error: Child process (/sbin/parted /dev/sdb mkpart --script primary 17408B 17179886591B) unexpected exit status 1: Error: You requested a partition from 17.4kB to 17.2GB...

Of course, partitioning by fdisk is not a problem, but how to define separate partition as volume for libvirtd service? And how to see defined partition in VM manager? I don't see guide.
