I am running a windows 7 guest on an Linux Mint 18.2 Cinnamon host. I have it running since a year now but I only use it one or twice a month. For a few months now, the guest keep freezing after a few minutes of use. Usualy I don't need it for a long time, so I manage with it, but it is quite annoying... So I decided to look into it and try to find what if wrong.
I tried a few things, but nothing worked ! So I hope someone here can help me.
The only message the log gives it a "vmmDevHeartbeatFlatlinedTimer" flag :
Code: Select all
00:02:46.247890 PIT: mode=2 count=0x2ead (11949) - 99.85 Hz (ch=0)
00:02:46.538055 PIT: mode=2 count=0x4ad (1197) - 996.81 Hz (ch=0)

00:06:42.087908 VMMDev: vmmDevHeartbeatFlatlinedTimer: Guest seems to be unresponsive. Last heartbeat received 4 seconds ago
Then, all I can do is to shut off the guest...
For a time, I thought it was the host running out of RAM, but after a few try, the problem also appeared with only 80% of the host RAM used, (and 0 swap) so it doesn't look like it...
I also activated and deactivated 2D and 3D acceleration, to no effect.
Any one have an idea ?
