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

[Jeroen Groenewegen van der Weyden <groen692@xxxxxxxxx>]

Hi,

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.
steps:
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).

mfg,
Jeroen

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

dom0
opensuse 11.4 x86
xen: unstable cs 23553

domu (HVM)
sles11sp1
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
