[Xen-devel] save/restore quality status report w/ r14854

["Zhao, Fan" <fan.zhao@xxxxxxxxx>]

Hi Keir,
I did a new round of test for save/restore w/ r14854 for bug verification, and 
your fixes have helped hvm save/restore a lot actually from my testing result.
Two critical issues for hvm save/restore have been fixed, they are:
  1) restore hvm guest will cause dom0 crash. Now the dom0 crash issue has been 
fixed.
  2) cp or scp files in guest with VBD or VNIF inserted and save&restore many 
times on pae host have problems. Now cp or scp will continue to work after 
restore many times.
However, there are some issues remained for save/restore, they are:
  1) save ia32e hvm guest with pv drivers has problem, the guest is 512M, but 
xm save command does not return, the guest is still alive and xm dmesg shows: 
　　　　(XEN) hvm.c:754:d4 HVM vcpu 4:0 bad hypercall 29.
    And s/r an hvm guest without pv drivers is okay.
  2) sdl guest will be restored as vnc one.


Best regards,
Fan
