KVM (L1) hits a #GP when trying to enable EFER.SVME, which leads to the #UD on VMSAVE (SVM isn't enabled). [ 355.714362] unchecked MSR access error: WRMSR to 0xc0000080 (tried to write 0x0000000000001d01) at rIP: 0xffffffff9228a274 (native_write_msr+0x4/0x20) Do you you see the same behavior on other kernel (L1) version? Have you changed any other components (especially in L0)? > Opteron_G5,check,+svm -hda c:\debian.qcow2 > > It's reproducible in 100% cases > > -- > You may reply to this email to add a comment. > > You are receiving this mail because: > You are watching the assignee of the bug. -- You may reply to this email to add a comment.
