Hello, everyone. I am new to Xen, I don''t know if Xen Driver Domain, network for example, support the HVM DomU, like a windows DomU? Can the windows DomU connect to Internet through the network driver domain without problem. The system is Debian squeeze 6.0 x86-64 with xen-hypervisor-4.0-amd64, xen-qemu-dm-4.0, xen-linux-system-2.6-xen-amd64. Best Regards! Ben

Another option in special cases could be using PCI or USB passtrough to your DomU - makes you able to connect even real hardware connected on the host machine. hth cheers, Niels. - -- Niels Dettenbach Syndicat IT&Internet http://www.syndicat.com -----BEGIN PGP SIGNATURE----- Version: APG v1.0.8 iIEEAREIAEEFAk76Fy86HE5pZWxzIERldHRlbmJhY2ggKFN5bmRpY2F0IElUJklu dGVybmV0KSA8bmRAc3luZGljYXQuY29tPgAKCRBU3ERlZRyiDWL0AJoD690nzSeg 92iof6WrN/96zdRr8wCdGE5hPVZ/ymqtfH7BNGOiV+kqNv8=kF7V -----END PGP SIGNATURE-----

Afaik there''s no xen-netback for Windows. So currently Xen Driver Domains can be only Linux/BSD/Solaris.> Can the windows DomU connect to Internet through the network driver > domain without problem.Any domU can use the Driver Domain. Usually Driver Domain is dom0, but for various security/isolation/performance reasons you might want to use other Xen Driver Domains aswell.> The system is Debian squeeze 6.0 x86-64 with xen-hypervisor-4.0-amd64, > xen-qemu-dm-4.0, xen-linux-system-2.6-xen-amd64. > > Best Regards! > > Ben >-- Pasi

I think he was asking about "Xen Driver Domains" concept, where the Xen backend driver (xen-netback) is running in a domU instead of dom0, providing disaggregated system with more security/isolation. -- Pasi
