Hi, i have exactly the same problem with my quad opteron 6174 hosts. (no problem on intel ).
my hosts are running proxmox 1.7 distrib (debian lenny with 2.6.32 kernel backported from squeeze). my ubuntu guests can boot with 2.6.32-24 kernel in smp mode, but since 2.6.32-25 they are hanging at grub. 2.6.35 maverik kernels doesn't work. i had try to upgrade my host kernel to 2.6.35, same problem with my guest. also, i had tried debian squeeze guests, i have the same problem with debian 2.6.32 kernel. Tell me if I can help ..... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/714335 Title: KVM SMP Linux Guests Hang -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
