Is it possible to assign two controllers of dq45cb to two guest VMs respectively?
hi, dq45cb has two display controllers as below and two display interface DVI-I 和 DVI-D. 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) Question 1: Is it possible to assign two controller to two guest VMs respectively? Question 2: must VGA compatible controller be used when reboot/startup ? there is no option in BIOS bios select 00:02.1 to startup. thanks. huiming. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

However, there is no guarantee that the cards or the drivers will work correctly if you do so -- that depends entirely on the hardware. You'll just have to try it yourself and see if it works. :-)> Question 2: > must VGA compatible controller be used when reboot/startup ? there is no option in BIOS bios select 00:02.1 to startup.Presumably because the BIOS only has a VGA driver, and so can't control the other one. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
