[pve-devel] pvedaemon hanging because of qga retry

I can't reproduce this high load, so I can't say.
My main concern is to not wait for a down daemon. (which will never response).

If we can be sure that daemon is running, with high load, simply wait for a response with a longer timeout.

Seems this patch does not solve the 'high load' problem at all?
