[win-pv-devel] Question about strange things in windows 7 domUs save/restore

Trying new windows pv drivers I found in qemu log with xen platformtrace enabled a strange thing:

xen_platform_log xen platform: XENIFACE|FdoRegistryThreadHandler:WriteRegistryxen_platform_log xen platform:XENIFACE|FdoInitialiseXSRegistryEntries: no such xenstore keyxen_platform_log xen platform:XENIFACE|FdoInitialiseXSRegistryEntries: Failed to initialise registry(c0000022)

Is there something to remove or add? (probably about xen hypervisor-onlysystems)

---

I'm also trying for a long time to solve one stringe problem of 2-3minutes "windows freeze" with qxl after restore and using spice.

These memory areas that seems not restored can be the cause of this problem?

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

Thanks for any reply and sorry for my bad english.


Here the full qemu log after restore:
