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.
