[Xen-users] PCI Digium TDM410p paravirtualization passthrough
Hello everyone! My name is Paul. I am a KVM user and I need to assign a PCI card to a virtual machine. OK! But the host motherboard I have available does not support VT-d, then with KVM no way to assign a PCI device to the VM. A developer of KVM suggested me Xen because told me that support paravirtualization devices passthrough. Practically the motherboard that I have available, mounts an Intel G33 chipset with a controller 82801IR (this is the mb: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01324212&lc=en&cc=ca&dlc=en&product = 3691066). Ultimately I virtualize OpenFiler distribution with direct access to 2 SATA drives installed on the host and then a distribution of Asterisk with direct access to a PCI Digium TDM410p. In both cases I think to use the paravirtualization. You think I can achieve this by using Xen type 1? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Also it''s pretty common scenario to use Xen to passthrough a PCI card to Asterisk VM. -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Ok. Thankyou Pasi. I googoled to find a guide about passthrough..are there official tutorials? And with passthrough tecnique, can I attach directly 2 phisical disk to a PV guest?

That''s basicly functionality that has been in Xen for a long time. -- Pasi> -----Original Message----- > From: Pasi Kärkkäinen > Sent: 25/02/2010 13:17:02 > To: Paolo Rivetti > Cc: xen-users@lists.xensource.com > Subject: Re: [Xen-users] PCI Digium TDM410p paravirtualization passthrough > > On Wed, Feb 24, 2010 at 10:34:44PM +0100, Paolo Rivetti wrote: > > Hello everyone!
