Subject: [BUG] kvm crashes in 2.6.28-rc6-00007-ged31348
Date: Sun, 30 Nov 2008 19:34:01 +0000 [thread overview]
Message-ID: <20081130193401.GA7690@hades> (raw)
Hi,
Maybe this is duplicated bug report, but since I was not able to find any
reference to it, I am reporting it anyway.
I am running 2.6.28-rc6-00007-ged31348 on x86_64.
I just tried to start kvm and got the following:
