Re: [kvm-devel] [ANNOUNCE] kvm-55 release
Hi Avi, I'm having issues with kvm-55. Was running a winxp sp2 guest all day yesterday with no problems. Shut down the guest at the end of the day. Boot up guest this morning and was not able to get any network on the guest. Networking on host was working fine. Shut down the guest. Started it back up but guest hung on startup. The latest stable version in my experience has been release 51. I have had issues with later releases. Releases 54 and 55 have both had issues with networking for me. Thanks.

(kvm-47 ???) one more thing is that beside you i dont know anyone who get this kind of error, is it ever happen to you when you dont use kvm? is your guest image is something special?, can i some how do anything that will give me the same result on my host? at lkml Dave Jones say that many of thease can be hardware problem (i would count more that it is kvm bug, but maybe it is worth trying memtest) http://lkml.org/lkml/2007/10/16/295 but one big hint for me will be if you will be able to tell if the problem start right after kvm-47 and never before it. - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
