I've tried that - no change.  Although as far as I can tell the qemu-kvm
in the SL 6.2 security updates (which I was originally running) is the
same version that is shipped in 6.4, so wasn't upgraded.

As mentioned, I've not found any especially good documentation online
specifically referring to Scientific Linux / RHEL, etc. But something I
did find suggested that RHEL doesn't support live snapshotting but RHEV
does.  I don't know how accurate this is or how it relates to Scientific
Linux though.



Hi Steve,

You can try asking the developers directly over at

   Spice-devel mailing list
   spice-de...@lists.freedesktop.org
   http://lists.freedesktop.org/mailman/listinfo/spice-devel


No offence, but maybe sending people to the right place is a good idea.
  SPICE is related to both KVM and QEMU, but it's still not the same
thing.  Same same but different, kind of.  So may I recommend one of
these lists instead?

* KVM mailing lists and IRC channels
http://www.linux-kvm.org/page/Lists%2C_IRC

* QEMU mailing lists
http://wiki.qemu.org/MailingLists


They take questions from the general public.  (They
can get "cranky" though.)


Yeah, I can understand that though ... asking about things in the wrong
list can also cause such issues.

Hi David,

Ooops.  I am on both KVM's and Spice's lists and copies and
pasted the wrong group.  I though I saw what I saw.  Thank
you for sending Steve the correct links.

RE: KVM live snapshotting

2013-07-19 Thread James M. Pulver 
Whenever I tried to talk to the KVM IRC channel, I get told I need a much newer 
version than RedHat ships in EL and they don't support the old version in EL... 
So I wouldn't get my hopes up.
