Xen users - Jan 2012 - problems with intel S5000VSA board and hvm

Hi @ll,

i use an intel S5000VSA server board with two xeon cpus. I installed a
debian squeeze amd64 system with debian xen and qemu packages.

Before i installed xen i check out successfully the virtualization flag
of cpus by

grep "vmx" /proc/cpuinfo

After installation of xen
(http://wiki.debian.org/Xen#Installation_on_squeeze) i can not run a hvm
domu.


xm dmesg | grep -i vmx

shows me this:

(XEN) CPU0: VMX disabled by BIOS.
(XEN) VMX: failed to initialise.


But the intel vt is enable in bios.

I change my grub config and add iommu=1 without any success.

menuentry ''Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN
4.0-amd64'' --class debian --class gnu-linux --class gnu --class os
--class xen {
	insmod part_msdos
	insmod ext2
	set root=''(hd0,msdos1)''
	search --no-floppy --fs-uuid --set 089f2a89-aa2b-4d22-bd01-32e70741eb3b
	echo	''Loading Linux 2.6.32-5-xen-amd64 ...''
	multiboot	/xen-4.0-amd64.gz placeholder iommu=1

	echo	''Loading initial ramdisk ...''
	module	/initrd.img-2.6.32-5-xen-amd64
}

What can i do to enable hvm support?


Best regards
Stefan

I have a SR1550 server which has the same or almost the same board.
So far I never tried running a HVM domU on it, but I can try it for you.

Can you first please update your BIOS and also tell me the version
you''re using? Please also check if there''s any extra switches
for
enabling IOMMU (i.e. IO-AT, VT-d, VT-x, VT-io, VT-bla,
VT-you-name-it).

And please email us a xm info + cat /proc/cpuinfo

With all that info maybe someone can see a problem without time
consuming bug hunting :)

I had the same issue. Before that I switched on VT option in the BIOS, but it
activates only after full poweroff.
