Hi,

On a few select VEs we're getting the following problem while online migrating:

Setting up checkpoint...
	suspend...
	get context...
Can not get context: File exists
Checkpointing failed
Error: Failed to suspend container

Can't really find anything in the logs about this either. Any pointers?

Hello, I have got the same problem as yours.

kernel : 2.6.32-5-openvz-686 (debian host)
guest : debian squeeze running irc server (ircd-hybrid) + sshserver + tinyproxy

I have the same error message when I try to make an online migration. The issue described in the bottom link is not the same, as my kernel is more recent than the one listed.

I can migrate other guests with no problem. Right now, I am trying to pinpoint the process causing this error on the guest.

Same problem here with Gentoo guests.

Kernel : 2.6.32-4-pve

I can successfully online migrate a Debian guest, but not my Gentoo.

No informations found on Google, into vzctl source code, and with strace.

Can somebody inform us about the "get context..." operation, this would help to debug.
