guest disk accesses lead to ATA errors + host vcpu0 unhandled wrmsr/rdmsr
Hi.
This is from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717724.
Using Debian sid with 1.5.0-5 my Linux VMs (also Debian sid) are broken. When they boot I get gazillions of ATA errors inside the guest, as well as:
[ 242.479951] kvm [7790]: vcpu0 unhandled rdmsr: 0x345
[ 242.483683] kvm [7790]: vcpu0 unhandled wrmsr: 0x680 data 0

[ 242.988598] kvm [7790]: vcpu0 unhandled rdmsr: 0xce
in the host.
Please have a look at the Debian bug, for screenshots and more info.
The problem didn't occur in 1.5.0-4 and there were basically no changes inside the VM (i.e. no kernel upgrade or so).
Thanks,
Chris.
