Could it be a memory issue? How much ram do you have in your system and how much is assigned to each vm?

 

[agreen]

RAM usage 86,50% (26,55 gib of 30,69 gib)
Swap usage 99,55%

i set for this 2 VMs 3.5 GiB Ram and now the VMs working.
i will check it for some days and will give an update

With that Swap usage, I'd say it was definitely due to over commitment of RAM. In general, try to ensure that the total memory assigned to all running VMs is less than the total available system memory. Otherwise a memory build up in one VM can crash the system.
