From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051129 Fedora/1.5-1 Firefox/1.5 Description of problem: When I boot the DOM0 kernel, the machine boots the whole way through starting all the services, including xend, then hangs. Keyboard/mouse are not responsive. If I "chkconfig xend off" and then reboot, I can login just fine. However, as soon as I "service xend start", I experience the same hang. Once hung, CTRL-ALT-DEL doesn't reboot the system - a hard power-cycle is required. No kernel messages are visible on screen. I'll attach an lspci output to the bug report in a second. Version-Release number of selected component (if applicable): kernel-xen-hypervisor-devel-2.6.12-1.13_FC5 xen-3.0-0.20051109.fc5.4 How reproducible: Always Steps to Reproduce: 1. Boot xen0 kernel, hangs at end of boot process OR 1. Disable xend service 2. Boot xen0 kernel 3. Login 4. service xend start Additional info:

We have rebased the hypervisor, kernel and xend significantly for fc5t2; can you reproduce the problem with the new packages? Thanks.
Can I test this by "yum update" to the latest devel tree, or do you want me to specifically install FC5T2? By the way, I did pick up some new Xen kernels etc. a short while ago (couple days, or a week or so) and this particular bug was gone, but Xen still didn't work very well. I'll check back on the exact versions, and whether there are any new updates in devel, and post another comment shortly.
Yes, the latest devel tree should be fine; from the perspective of Xen, it's more or less the same as fc5t2 still. Thanks!
This is expected to be fixed in rawhide; please reopen if the problem persists.
