KVM server freezes, then refuses to start org.freedesktop.systemd1.UnitExists: Unit 1011790.scope al

[encore]

Hi,

we are facing issues for some time now, where KVM servers suddenly freeze. We need to stop them trough proxmox and then try to start them again, but it immediately says:

Total translation table size: 0
Total rockridge attributes bytes: 971
Total directory bytes: 6144
Path table size(bytes): 58
Max brk space used 17000
180 extents written (0 MB)
TASK ERROR: start failed: org.freedesktop.systemd1.UnitExists: Unit 1011790.scope already exists.

any ideas?

This means that the scope of the KVM machine still exists.
I guess a KVM process of this machine still exists, please check.

yes indeed, figured out with

ps -ef | grep <VMID>

and killed it with kill -9 afterwards.
Anyway, the scope message persists.

Facing this issue on several nodes, different VPS and on different windows OS.

Some nodes do have this kernel:

Kernel Version Linux 4.15.18-10-pve #1 SMP PVE 4.15.18-32 (Sat, 19 Jan 2019 10:09:37 +0100)

Some this:

Kernel Version Linux 4.15.18-12-pve #1 SMP PVE 4.15.18-35 (Wed, 13 Mar 2019 08:24:42 +0100)
