Check if VT is enabled
Hello group,
I recently purchased an HP m7360n computer which has an Intel Pentium D 920
processor in it. Unfortunately there is no BIOS option to enable or disable
VT. The board it sits on uses the Intel 945P chipset.
If I am in linux and do a ''cat /proc/cpuinfo'' I get this:
[root@localhost ia32]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel

[PATCH][discuss] evtchn race condition
Keir,
below/attached patch is necessary to allow SVM partitions to boot
unmodified guests with xen-unstable.hg c/s 8961. c/s 8822 and 8828
(some necessary evtchn modifications) cause SVM partitions to fail with
"lost interrupt" hda error during boot.
We currently do not understand why these modifications are necessary and
in fact, a race occurs with one part of the patch (added

Question about Intel VT on PowerEdge
Hi, I''m runing a Fedora Core 6 on a Power Edge with Xeon Cranford that I
planning to running Windows as a guest S.O. and reading "Fedora Xen
Quickstar FC6" as document to install Xen on this server.
This document recomend a "grep vmx /proc/cpuinfo" test to verify if computer
is Intel VT supported. Running this command I don''t find any information
about vmx.

how to enable VT
Hi,
I have a Dell opt 755 machine and installed Xen 3.3.1. The CPU is core
2 due E6550, which as the vmx flag. However, when I reboot the machine
to xen 3.3.1. I can not find vmx in the /proc/cpuinfo. But vms appears
in the kernel 2.6.29 (not xen kernel).
Can anyone help on how to enable vt in this machine?
Thanks.

Intel VT-d Support
Hello all,
please tell me, how can I be sure that
my Xen installation is built with Intel VT-d support?
Something like
xm info | grep -i KEY-REGULAR-EXPRESSION
xm dmesg | grep -i KEY-REGULAR-EXPRESSION
What line I should look for?
And if it''s really built with it,
how can I be sure, that Xen has successfully
initialized VT-d hardware?
I have read [1] and the lists archives

VT-x not found..
Hi Everyone,
I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:
http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/
Now, using the new kernel that it gave me, the system doesn''t seem to be
able to detect vt-x..
In virt-manager, Local Install Media and Network Boot are greyed out..
Any ideas?
Thanks

Trouble enabling VT-D: "I/O virtualisation disabled"
I have a chipset which supports VT-d (Intel X58) and, according to my
motherboard manufacturers, VT-d is enabled in the BIOS and listed as "Intel

VT or paravirtualization?
Hello,
What is the better solution now to run linux domUs under Xen3?
Using a VT hardware, sould I install a xen-patched kernel as I would
where no VT extension, or use an unmodified linux guest system?
Is there any performance difference between a Pentium D 3 Ghz with vt
(9xx) and without it (8xx)?
Regards,
Slapic

Problem bringing up 32-bit Sles 9 on a Dom-VT
All,
We are facing some issues bringing up a DomVT on Xen x86_64(changeset
9267).
We created a disk image with dd 8 G in size.
We then booted an associated Dom-VT with a CD-ROM and did net-install of
the sles-9 OS.
This completes successfully.
Then, when the system is brought around for a reboot (having changed the
boot option from cdrom to disk), the system hangs after the line

VT-d not working
Hello there,
I am using a Gigabyte H55M-UD2H (Intel H55-Chipset) together with a
Core-i5-650.
According to Gigabyte Support the Mainboard does support VT-d. Well,
actually support says, that VT-d does work on Windows-7 in XP-Mode.
They do not test and support Linux though.
Did anybody here have success using VT-d on any H55-Board?
Perhaps it is some misconfiguration on my side. I tried a

Hi,
I really need help. I spent 2 days already on this pci passthrough thing.
I''m using Xen 3.2.1 with Centos 5.2 64 bits on intel VT. I''d like to

I''m trying to pass PCI 12:01.0 to my domU guest.

VT-d support in HVM?
Hi,
I''ve recently setup a few machines with 3.2 64bit without any unresolvable problem.
These machines all run pv domU''s and a view "basic" hvm domUs.
As I''ve got one machine left for internal use and testing, I would like to take a
look at pciback with VT-d support (bios screen shows a VT-d [enable|disable]).
My question is, do I need to add patches, or use
