Its probably related to memory fragmentation somehow...
My system has 256GB of ram total, one VM uses 48GB.
After a reboot the VM comes up easily.. but after some time it wont or takes ages.
If I check hugepages for example it seems fine
My zfs ARC is at > 100GB. Which I dont really mind.. but I thought it would free up space if needed etc.
So yea... it's not a soluation to "reboot the host if that happens". There is RAM, there are huge pages available etc etc but the VM sometimes still wont come up.
How do I best address this?
