Greetings, Could someone post an example configuration file that enables ethernet, usb, hard drives and cdrom for a fully virtualized RHEL domain? Your help is greatly appreciated. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
RHEL HVMHi, I have been looking at doing a similar thing (just ethernet, multiple cards though) with a RedHat HVM. As far as I have read though, it is not possible to do this with an HVM, only a PV system. Can anyone confirm this, because it''s been very hard to find any actual information regarding this. It''s mostly one off comments and suggestions so far. Any help appreciated, Phil. ----- Original Message ----- From: Johnson, Tony M To: xen-users@lists.xensource.com Sent: Thursday, March 13, 2008 11:48 AM Subject: [Xen-users] RHEL HVM Greetings, Could someone post an example configuration file that enables ethernet, usb, hard drives and cdrom for a fully virtualized RHEL domain?

You''re looking at PCI passthrough, right, Phil? I''m not sure what the original e-mail was about (Tony ... ?). Anyhow, on to your question:> I have been looking at doing a similar thing (just ethernet, multiple cards > though) with a RedHat HVM.

It''s mostly one off comments and suggestions so far.You can''t do PCI passthrough to HVM guests without IOMMU hardware (and a sufficiently new version of Xen). There are some (very recent) systems that do have the hardware support required - e.g. Intel''s VT-d. There''s been some development work on passing through PCI devices to HVM guests without IOMMU support but it''s not in the mainline Xen tree yet. You can configure HVM guests to pass through USB devices to guests, even if the dom0 doesn''t have a driver for that device. I''ve heard varying reports of the performance / stability of this but it might be worth a try! You can boost performance of HVM guests by installing paravirt drivers for block and network. There''s even a GPL licensed set of PV drivers for Windows being developed by James Harper and Andy Grover.
