Re: [Xen-users] How to check whether a windows domU has PVDrivers installed in Domain-0

["kevin.zhang@xxxxxxxxxxx" <kevin.zhang@xxxxxxxxxxx>]

Hi, Ian.Campbell,

     Thank you for your suggestion.

     Now I can judge pv drivers with evt-ch and ring-ref now.

     

Best Regards,

I'm not sure if there are any direct ways, but you could infer by

examining the "state" node in the backend xenstore directory for each

device.

 

I'm not sure if you can infer anything from e.g. "xl block-list". e.g.

the presence/absence of an evtch or shared ring entry.

Ian.
