On xen 4.5 (tried with qemu 2.0.0/2.1-rc0, spice 0.12.5 and
client with
spice-gtk 0.23/0.25) windows 7 domUs with qxl vga works good
as kvm
except for one problem after xl save/restore, when after
restore on
spice client connect  the domU's screen freezed for 2-3
minutes (and
seems also windows), after this time seems that all return to
works
correctly.
This problem happen also if spice client connect long time
after restore.
With stdvga not have this problem but stdvga has many missed
resolutions
and bad refresh performance.

If you need more tests/informations tell me and I'll post them.

Client and server logs would certainly help. Please run:
   * virt-viewer with --spice-debug option
   * spice-server with SPICE_DEBUG_LEVEL environment variable set
     to 4 or 5 (if you use qemu+libvirt, use qemu:env element:
http://libvirt.org/drvqemu.html#qemucommand )
and note the location in the logs where the freeze takes place.

David


Thanks for your reply, in attachments:
- domU's xl cfg: W7.cfg
- xl -vvv create/save/restore: xen logs.txt
- remote-viewer with --spice-debug after domU's start until xl
save: spicelog-1.txt (zipped)
- remote-viewer with --spice-debug after domU's xl restore:
spicelog-2.txt


Sorry for my forgetfulness, here also qemu's log:
- after domU's start until xl save: qemu-dm-W7.log.1
- after domU's xl restore: qemu-dm-W7.log


If you need more tests/informations tell me and I'll post them.

Thanks for any reply and sorry for my bad english.

Tested on latest staging (commit
7d203b337fb2dcd148d2df850e25b67c792d4d0b) plus the spice patches:
https://github.com/Fantu/Xen/commits/rebase/m2r-staging

If you need more informations or tests tell me and I'll post them.
Thanks for any reply and sorry for my bad english.


I did another tests updating to latest git staging (commit
3e2331d271cc0882e4013c8f20398c46c35f90a1) and is nomore problem of
"only" 2-3 minutes but now when it appears to restart (after 2-3
minutes) windows domUs undefinitely hangs instead.
No further details in xen and domU's logs.

If you need more tests/details tell me and I'll do them.

Thanks for any reply.


I did a new test with xen build based on tag 4.5.0-rc2 and on xl
dmesg show these errors:

*(XEN) hvm.c:6119:d5v0 Bad HVM op 23.*

Before and after save/restore, with stdvga instead not show them.


Sorry, I found that was introduced by new winpv drivers update
instead and I solved applying this patch:
x86/hvm: Add per-vcpu evtchn upcalls v3
http://lists.xen.org/archives/html/xen-devel/2014-11/msg00752.html
About save/restore problem with qxl I still not found a solution or
at least the exact cause :(


I tried a strace on qemu process when windows (in domU) is in temp.
freeze and still does many operations (seems similar), I post below a
small part if can be useful.
I noted for example some of these lines:
read(8, 0x7fffb5d09ac0, 16)             = -1 EAGAIN (Resource
temporarily unavailable)
Is it normal?

Strace of domU's qemu process during freeze can be useful? I must do
a more specific tests?
If you need more informations/tests tell me and I'll post them.


xen save/restore seems don't save hvm domUs vga's videoram but
kvm/qemu save yes, is it correct?
can be the cause of problem and/or other problem?


I tried also remote-viewer with --spice-debug and after restore
connecting with it show initial screen image correct, freeze after with
line:
    (remote-viewer:3300): GSpice-DEBUG: channel-main.c:1185 main-1:0:
monitor config: #0 1364x668+0+0 @ 32 bpp
and after some second spice screen become black and show these:
    (remote-viewer:3300): GSpice-DEBUG: channel-cursor.c:480
cursor-4:0: cursor_handle_reset, init_done: 1
    (remote-viewer:3300): GSpice-DEBUG: channel-display.c:1744
display-2:0: 0: FIXME primary destroy, but is display really disabled?

this can be related to the "freeze" or is only a conseguence?


Thanks for any reply and sorry for my bad english.


Below I posted full xl dmesg of domU, if you need more
informations/tests tell me and I'll post them.
