hi,
im am running pve-manager/3.4-1/3f2d890e (running kernel: 3.10.0-7-pve) on one node.
some virtual machines consume a lot more memory then they should.
i put for exmaple fixed 16GB for the machine id 212- and top shows me RES 22.3 and VIRT even 29GB!
i am not able to start more vms as the server says Cannot allocate memory
any ideas how this can happen?
bellow a dump of ps from one of the vms consuming to much ram...
