The Foreman VM only uses 1GB at the beginning and MOM over time reduces = the memory size from 8GB Ram to the defined minimum of 2GB mom.log: 2016-03-18 12:25:42,669 - mom.Controllers.Balloon - INFO - Ballooning guest= :qvie-foreman from 2210584 to 2100054 2. When the VM needs RAM very quickly like if you do an 'cp /dev/zero /run/= zero' the ovirt guest agent crashes with an out of memory error. ovirt-guest-agent.log: Traceback (most recent call last): File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", line 239, in doWo= rk self.sendUserInfo() File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", line 355, in send= UserInfo cur_user =3D self.dr.getActiveUser() File "/usr/share/ovirt-guest-agent/GuestAgentLinux2.py", line 325, in get= ActiveUser users =3D os.popen('/usr/bin/users').read().split() OSError: [Errno 12] Cannot allocate memory 3. Resulting in an MOM warning that it can't get any memory stats from the = VM. Leaving the memory size at its minimum size:. mom.log: mom.Collectors.GuestMemory - WARNING - getVmMemoryStats() error: The ovirt-= guest-agent is not active Any chances to prevent that from happening? Or is this a bug in MOM / ovirt= -guest-agent that should be fixed?
