Hi Steve, This was indeed broken for Jiang without the patch applied. Jiang raised issue with me via email. I've cut and pasted the part of the email describing the issue:
"Hi, Leann, when I run KVM guest in ubuntu 10.04 (lucid amd64) with 32bit qemu, I noticed the 32bit qemu always seg fault because the %gs register is clobbered after KVM_RUN ioctl." Jiang subsequently test a patched kernel I provided and confirmed it resolved the issue. Confirmation was sent to the kernel-team mailing list: https://lists.ubuntu.com/archives/kernel-team/2011-May/015656.html "With this patch, the 32bit android emulator works quite well. I already update the bugzilla. Leann, really appreciate your quick response!" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787675 Title: Fix up bodged backport for KVM: VMX: Fix host userspace gsbase corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/787675/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
