Xen project Mailing List

Hi Ananthan,

Our expert on this is on holiday at the moment so his reply to this will be delayed. In short: the drivers currently rely on a number of XenServer-specific patches to Xen and qemu so won’t work on vanilla Xen. The plan is to upstream patches where appropriate and make changes to the driver where patches cannot be upstreamed.

Regards,

James

Subject: [xs-devel] vif failing after installing Citrix pv drivers on xen 4.2

Hi,

I am trying to make Citrix PV drivers to work on Windows 2008R2 guests running on Xen 4.2.

But for some reasons guest is not able to boot after installing pv drivers.

After commenting vif from configuration file guest booted up with pvdrivers for Disk.

brctl show shows guests vif for some time and later got removed.

In vm log its showing :

XEVTCHN: ERROR: Failed to set up device suspend/event-channel.

XEVTCHN: USER: SLGetWindowsInformationDWORD(VirtualXP-licensing-Enabled) failed (c004f012)

XENUTIL: WARNING: AdapterConnectBackend: timed out in XenbusWaitForBackendStateChange: /local/domain/0/backend/vif/271/0 in state INITWAIT; retry.

Do i need to make any changes to make network driver to work
