I wonder if you could share pachest that you listed in your test.

I posted all patches applied in my test.

Posted one year or more ago as first of 3 methods to add spice on upsteam qemu compile but rejected because the latest stable version of major distribution all haven't spice prerequisites, I recently ask if is possible to reconsider it, but no reply for now:

Taken from debian package but must be done with better configure patch.
Awaiting Ian news about that, probably he has already done a draft for xen configure and also also upstream qemu.

Posted last year but rejected.


There is also another patch about qxl support and I waiting about adding of SSE support on hvm domU for have it full working.

Did you test with large memory assigment ?

1 and 2 gb of ram on my test domUs.
FWIK the large memory assignment is problem only with pci passthrough (I'm not using that by now).
For now I use ram > 2gb only with rare pv domUs in production, if necessary I'll test large memory also on spare system and also with hvm domUs.

Tried fast test on w7 64 bit domU with 4 gb of ram, with built-in qemu 1.3 it works, while with qemu 1.5.1 doesn't (on start it does not see the virtual disk, while with 2 gb of ram works)

Wheezy 64 bit with kernel from package linux-image-3.2.0-4-amd64 version 3.2.46-1 and all dependency packages for xen, spice and usb redirection.
Seabios 1.7.3-1, qemu 1.5.0+dfsg-5 (1.5.1), spice 0.12.4-0nocelt1 and usbredir 0.6-2 compiled from debian unstable sources.

git clone git://xenbits.xen.org/xen.git (in this build commit is 6072b7c808043b6886c33f896e06fc32ee28346e)
-------------------------
Added some patches:

-------------------------
./configure --prefix=/usr
-------------------------
make debball

Note:
I tested both upstream qemu of xen git and debian unstable packages.
On this test I removed blktap2 (after see disabled for next version of xen debian package), no regression found with qdisk and performance significantly improved. One benchmark result on windows 7 64 bit domU on attachment.

-------------------------
Old issue:
- Network is not working after restore on Windows domU with qemu-xen and gplpv
  Workaround: fixed mac address
-------------
- Starting xendomain with "xl create" show some debug options:
  Starting auto Xen domains: W7.cfgxc: info: VIRTUAL MEMORY ARRANGEMENT:

[done].
I think it is would be better hiding them here
-------------
- on W7 pro 64 bit domU error in the begin of qemu log, while domU seem to work:
xc: error: linux_gnttab_set_max_grants: ioctl SET_MAX_GRANTS failed (22 = Invalid argument): Internal error
xen be: qdisk-832: xc_gnttab_set_max_grants failed: Invalid argument
-------------
- nested hvm was bugged: started test it on windows 7 pro 64 domU on qemu-xen,
  xpmode crashed on install without show error, no error on logs and havdetection works
  Now xpmode install and start correctly except integration features
  (disks,printers,clipboard sharing) and usb passthrough (of xpmode)
