[Xen-devel] Reproduced error when creating Intrepid HVM at Xen Unstable Dom0(vmlinuz-2.6.29-rc5-tip)

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

After fresh port Xen Unstable:-

No patching has been done due to zero awareness what to apply.

"If we assign the device that doesn't have Power Management Capability
Structure to guest domain, qemu accesses NULL pointer."

I am getting the same error
"xs_read(/local/domain/0/device-model/2/xen_extended_power_mgmt): read
error"

Yuji said "I'll submit the patch to fix the bug ASAP", I will try
again once his patch is submitted.
