Berrange" Cc: xen-devel@lists.xensource.com, Dave Cameron List-Id: xen-devel@lists.xenproject.org Hi, Our current PV on HVM drivers are based upon work that was submitted to xen-devel back in April. As you might recall, our focus has been concurrent support of 32 and 64 bit fully virtualized domains, and all of our work supports this. I'm sure that the concepts of what we've done, and what was placed into the open source project starting in July, are quite similar. However, given the time frames involved, and the base work not being included back in April, I also have no doubts that the interfaces aren't identical. As noted, we have these drivers running and performing extremely well at our beta customers. We support concurrent usage for both 32 and 64 bit user domains. The Linux code was released a short while back, and is open source and available for download on our website. The Windows drivers were completely developed in-house, and there are currently internal discussions about whether or not we will release them as open source. -b Daniel P.
