Furhter info:

Found Bios version f13s at Gigabyte- site that supposedly should support VT-d (in ESXi?), but it has not helped.

Is there need to specify IOMMU support in Ggrub.conf for XCP 1.5 (Xen 4.1.1)? If so, how do I go about it? Can't find /boot/grub/grup.conf.

Kind regards,

Gigabyte GA EX58 UD5 Bios version f13 (AwardBIOS) (newest)


SmartVirtualization is enabled in Bios.

Xen-dmesg output:

[root@xenserver-jafi7 ~]# xe host-dmesg
(XEN) Bad console= option ''
(XEN) Freed 216kB init memory.
(XEN) __csched_vcpu_acct_start: setting dom 0 as the privileged domain

Seems to me that both CPU and Chipset are listed as supporting VT-d, but motherboard (bios) is not listed as such.

Anyhting that can be done? Can I gather further info?
