I am on Ubuntu 11.10 64bit and testing Ubuntu12.04 in kvm-qemu0.14.1
+noroms-0ubuntu6.3 on it.
On running Ubuntu12.04 in kvm-qemu my Ubuntu 11.10 host kernel throws
ata exeptions of different kinds.
One high repeated:
Mar 26 13:44:07 ubuntu kernel: [ 3941.779080] ata1.00: exception Emask 0x50
SAct 0x1 SErr 0x480800 action 0x6 frozen

Handshk }

Mar 26 13:44:07 ubuntu kernel: [ 3942.276491] ata1.00: configured for UDMA/133
Mar 26 13:44:07 ubuntu kernel: [ 3942.292077] ata1: EH complete
Interestingly the ata entries stopped when I switch of the Ubuntu12.04 guest.
They may be caused by guest Ubuntu12.04 kernel3.2.x I/O errors which I
could observe there in.
I will attachadditional the 12.04 guest logs when and if I get it manage
to access them.
Anyway, the host kernel(3.0.x series) should not be affected of guest
kernel misbehaviour. This me cause in short time a corrupted filesystem.
