[Xen-users] Problems saving domain
Hello,
I have the problems if I want to save the running domU on Xen
3.0.4.1 - the save always fails. In the xen log there i found following
debug info:

The Problems occurs even if the targent domain is w2k server 32
bit or w2k3 server 64 bit, no difference (maybe the numbers behind the
"save" are different by the given two domains...
I have enough space on the disk etc.
Does anybody has a solution for it? Is it my or xen error? I uer
as dom0 Ubuntu Dapper 6.06
Thanx in advance for help, Archie.

There is work in progress to fix this... I think this is a "required" feature for 3.0.5, so 3.0.5 should have working save/restore - Live migration may or may not be included in that. -- Mats -- Mats _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] Problems saving domain
Hi Mats, Thank You for the answer. Yes, it is Windows on HVM. With linux as domU it works OK. So it is clear. I have also the problem with the shutdown of such windows domain - the VM is always "turned off", so Windows are not shut down correctly (again, with Linux as domU it is no problem). What would You recommend, is there any possibility to get this both functionalities working for windows (also not with HVM), could You point me to some description how to configure it to get it working? Or is the only chance to wait for xen 3.0.5 or maybe later? Thank You very much for response, Archie. -----Original Message----- From: Petersson, Mats [mailto:Mats.Petersson@amd.com] Sent: Wednesday, March 07, 2007 12:11 PM To: Artur Linhart - Linux communication; xen-users@lists.xensource.com Subject: RE: [Xen-users] Problems saving domain> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > Artur Linhart - Linux communication > Sent: 07 March 2007 10:55 > To: xen-users@lists.xensource.com > Subject: [Xen-users] Problems saving domain > > Hello, > > > > I have the problems if I want to save the running > domU on Xen 3.0.4.1 - the save always fails.

The code needed to save/restore HVM domains isn''t there in 3.0.4, it''s only present in the "unstable" version of Xen. This version will become 3.0.5 in the next few weeks or so. I was the one who wrote the code to save the AMD CPU context, so I should know ;-) As to power-off in Windows, I thought that worked, but maybe there are different variants of how this works, which work differently - or maybe because I''ve been running unstable for several months, and it certainly works in unstable (well, I''ve never really done anything other than unstable, as I''m a Xen kernel developer when I''m not responding to posts here - there''s rarely much point in running the "released" version when you want to add new code to Xen) -- Mats> > Thank You very much for response, > > Archie. > > -----Original Message----- > From: Petersson, Mats [mailto:Mats.Petersson@amd.com] > Sent: Wednesday, March 07, 2007 12:11 PM > To: Artur Linhart - Linux communication; xen-users@lists.xensource.com > Subject: RE: [Xen-users] Problems saving domain > > > -----Original Message----- > > From: xen-users-bounces@lists.xensource.com > > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > > Artur Linhart - Linux communication > > Sent: 07 March 2007 10:55 > > To: xen-users@lists.xensource.com > > Subject: [Xen-users] Problems saving domain > > > > Hello, > > > > > > > > I have the problems if I want to save the running > > domU on Xen 3.0.4.1 - the save always fails.
