Subject: [libvirt] libvirk KVM save (migrate) terribly slow
Date: Thu, 10 Dec 2009 08:05:12 +0100 [thread overview]
Message-ID: <20091210070512.GA6384@develbox.linuxbox.cz> (raw)
Hi,
I noticed that using libvirt to save running domain is terribly slow,
I mean it can take even 10 minutes to save VM with 2GB RAM, although
the host is almost idle (8CPU, 16GB RAM). If I understand correctly,
libvirt first pauses the vm and then migrates it to file (optionally through gzip).
Restoring it back to running state is almost instant.
I guess this is not what should be expected, is there something particular
I should check?
Thanks a lot in advance
with best regards
nik
