Re: [Xen-devel] [PATCH 20 of 20] n2 MSR handling and capability exposure


Based on these patch series, I gave it go.
I noticed until now that the system becomes in-responsive a few second after activating the second nested guest.
1) dom0 creates domu (pass)
2) domU creates first kvm guest (pass)
3) domU creates second kvm guest (fail)
after the third step the domu becomes in-responsive. eg no network / vnc console response. in dom0 is shows domu is stil running.

I'm able to provide any input needed, just tell me what you need (and how).


My HW setup
mobo asus z8nr-d12
proc: 2 times e5645
mem: 96 GB

My goal/test
in short: HW -> dom0 -> domU -> 4 time kvm guest

opensuse 11.4 x86
xen: unstable cs 23553

domu (HVM)
mem: 8 GB
vcpu: 4

domu guests
1) qemu-kvm: propetary OS
2) qemu-kvm: propetary OS
3) qemu-kvm: SLES10SP3
4) qemu-kvm: SLES10SP3

Are you planning to fix this before checking in this series?  I'm pretty
sure that at least MSR_IA32_VMX_VMCS_ENUM should be trivial, since you
define your own VMCS format.

Sure, the updated patch is attached.
Thanks.  I've applied the full series.  I cleaned up a few things for
the 32-bit build as well.
