This is a serious regression. My testing suggests that this issue affects any guest which is assigned more than 578MB of RAM. (A guest configured in XenCenter with 579MB of RAM exhibits the fault, whereas the same guest reconfigured with 578MB boots fine.)
Victor, can you check whether reducing its RAM allocation allows your guest to boot? The failure mode is that the guest spins on 100% CPU on the first core, before any kernel messages are printed (even without the "quiet" option). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791513 Title: After upgrade to kernel 2.6.32.32.38 ubuntu don't start in Xenserver -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
