how does hypervisor isolates DomU from Dom0
I am not clear with the working of hypervisor xen.
How does an instruction executed by kernel in Ring0 of DomU gets
mapped or executed by hypervisor and then is excuted in Dom0.
Is this thing some where on the wiki page?

how can you boot an existing linux domU off the cdrom on sles11 dom0?
I have a sles10 domU running on a sles11 dom0. xen is version 3.4. We''re
trying to pass through a scsi card to the domU. We assign the domU the
scsi card through virt manager. When we try to boot the domU it won''t
boot. We need to update fstab and menu.lst, but we need to boot with the
hardware attached to see how it''s being seen by the domU.

Multiple Serial Port Passthrough in HVM domU
So, I made a mistake a bought four systems with the Intel Core i3 processors, without doing my homework to make sure that these systems actually supported VTd. Turns out there''s plenty of information out there indicating that the Core i3 processors do *not* support VTd. I was counting on VTd for two applications: Graphics Passthrough and passing through a PCIe 4-port serial card. Of

Problem in linux domU re: /dev/rtc and hwclock
Hi all,
One of our domU VMs (CentOS 5.6 x86_64) runs a cobol application,
which in turn called ''clock'' to get timestamps. Changing this is
non-trivial.
When I try to call ''clock --debug'' I get:
[root@vm0010 ~]# clock --debug
hwclock from util-linux-2.13-pre7
hwclock: Open of /dev/rtc failed, errno=19: No such device.
No usable clock interface found.

simple question - amd64 dom0, and PVM i486 domU ?
I''ve been looking for a solution that doesn''t involve dual booting, or
chrooting things to get my x86 domU to work. I have a Debian xen
server on an amd64 platform. It would seem that I should be able to
also install or force the install of a non-xen i486 kernel. When I
recieved this server it had a manufacturer''s install of Etch with an

Performance Issues: I/O Wait
Hey, everyone,
I''m having some issues with a Xen DomU right related to performance. We have an application that cross-compiles a Linux distribution from scratch for embedded systems. We''re attempting to run this application inside a Xen DomU (paravirtualized, modified guest kernel), and the performance is really bad. The culprit seems to be high I/O wait times related to the

Problems with GPLPV network latency
Hi,
DomU is a Win2008 R2 64
When i install the GPLPV drivers the network latency goes from 15ms to
random numbers up to 1200ms and eventually dies. If you run a ping from
the DomU to another host the network stays alive but the high latency is
still there.
Further more if i try and uninstall the network driver i am unable to
use the old one (realtek) as it cannot detect the device.

Xen and I/O Intensive Loads
Hi, folks,
I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

Hi
Is it true that the GPLPV drivers is incompatible with QCOW images?

If i use QCOW images with my Windows DomU''s i get a stop error:

GPL PV Intermitent Network Problems
Well, I seem to have developed a strange issue with the GPL PV drivers
in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows
XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two
of them, though, have started exhibiting a strange behavior with
intermittent network connectivity. Basically, the network starts up and
