Subject: xl vcpu-set crashes Dom0
Date: Mon, 28 Feb 2011 18:23:19 +0100 [thread overview]
Message-ID: <4D6BDA07.2010707@amd.com> (raw)
Hi,
as mentioned earlier today I had some issues with patch 22934, which
decreases the number of vCPUs for Dom0 in case of cpupool-numa-split.
I now found that this is not directly related to this patch, as it
triggers also with "xl vcpu-set". So far I tried the following combinations:
c/s 22956 on a machine with 48 physical CPUs:
not restricted dom0:
xl vcpu-set 0 6 => crashes
xl vcpu-set 0 47 => crashes
dom0_max_vcpus=6
xl vcpu-set 0 5 => crashes
xm vcpu-set 0 5 => crashes
The only message I get is:
root@dosorca:~# xm vcpu-set 0 5
(XEN) Domain 0 crashed: rebooting machine in 5 seconds.
Debugging turned out that for instance the libxl_set_vcpuonline()
returns without an error, but the machine then crashes afterwards.
Can someone reproduce this? Any ideas?
Regards,
Andre.
