[PVE-User] Live Migration Question.

[jameslipski]

Hi,

As an update, as I'm trying to understand why this is happening; at the moment, I don't see any sort of pattern. It happens at random under different guest OSs (mixture of Debian 8 and 9). As I've mentioned I'm not really seeing anything in syslog unless migrations events (and faults) are recorded elsewhere (with verbosity). Any help would be appreciated. Thank you.

However sometimes I run into an issue where the VM would migrate to the destination node, and dashboard reports "Internal-Error"; and from the console it looks like it's suspended. The only way I can kick it out of this state is to kill the process and start it again (or let HA start it again).
