[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re[2]: [Xen-devel] pv_ops DomU boot problem using pvgrub, xen 3.4.1-rc7, debian 2.6.26 dom0
Hello Jeremy,
Let's give some more info:
Xen: 3.4.1-rc7 (xm info attached)
Dom0 kernel: 2.6.26-2-xen-amd64 (standard debian xenified kernel)
DomU kernel: self compiled vanilla 2.6.30.1 kernel with pv_ops stuff enabled
I am trying to boot a PV domain with PVgrub, config attached
Hmm could it be related to the topic: "[Xen-devel] Re: [PATCH] x86: detect
use of extended APIC ID for AMD CPUs" ?
gdb returns:
0xffffffff813ce1df <read_pci_config+43>: out %eax,(%dx)
