Might want to give PCI latency setting a try, it helped for me. My ZTTEST
would drop occasionally to 99.95% until I set:

qemu disk cache mode
Hi all,
I can''t find any good talk about this subject and would like some insights
and advices on the cache side in xen.
I discovered that a domO power outage can lead to a severe filesystem
corruption of the domUs. The domO is a dual disk dell server with a PERC
controler in writethrough cache mode, the disk cache is disabled, the
scheduler in the domO/domU is NOOP, the domO is holding

Searched for a patch today, and all google found me was this mail asking
for one :-o
So I went ahead and coded one up. Attached.

domU does not see the pci nic - pci passthrough
Hi all!
I want to assign a physical network card (e100) to a domU:
I think Dom0 is ok but domU does not recognize the pci nic.

Into Dom0 I have

This is dmesg:

pci-passthrough to a pv domu worked in xen 4.2.2, but not in 4.3.0
Hello,
my dom0 is an alpinelinux installed with kernel 3.10.14-1-grsec and xen
4.2.2.
My domU is an opensuse 12.3 with all patches installed.
The system works great, but when I do only switch xen from 4.2.2 to
4.3.0 (packages from http://nl.alpinelinux.org/alpine/edge/main/x86_64/)
then my kernel in the domU does an Oops and the drivers for my dvb card
aren''t loaded successfully.

PCI Mapping of e1000 Dual-Port Adapter to DomU

I´m trying to map one network interface of a Dual-Port e1000 Server

PCI passthrough, poor network performance in upload direction
Hi all,
I have been having an issue for over a year with several Xen installations
and have not been able to find out if this is just something I am missing.
Basically I am trying to configure a firewall with two ethernet cards in a
domU using pci passthrough. I am hiding the Ethernet cards at boot time via
the pciback.hide kernel option.
Right now I am running Xen 3.3.0 and the two Ethernet

XEN - Routed and Bridget Mode together (mixed)
Hi,
is there any possibility to get a XEN DomO and DomU running with
bridget and routed mode together.
The reason behind this is, to get the requests via the official IPs to
the DomU''s (routed-mode) and the interworking
between the DomU''s with connected with help of the (bridged-mode).
I got it work, with setting everything up manually. But as I

xm top shows high CPU load on domU when passed PCI NICs after hypervisor update
I am running a 64 bit dom0 with a stock Debian Squeeze xen hypervisor
and kernel. On top of this I am running a PV 32 bit domU that is
passed two PCI network cards. This set-up had been working well for
over a year, however there was a recent hypervisor update so I
rebooted the dom0. Unfortunately now the domU that is being passed
the two NICs is no longer able to create a PPPoe connection to

Fully-Virtualized XEN domU not Booting over iSCSI
Hello,
I am currently trying to move my VMs from running on local host storage to
a shared storage (trying out iSCSI) but I am
facing a bit of a booting dilemma.
The domUs are a mix of paravirtualized and fully-virtualized VMs. They all
boot and run like clockwork when on local
storage.
The paravirtualized domUs appear not to have a problem when I relocate and
boot them from the shared storage

I''m a newbie to Xen.
I installed a DomO CentOS 5.2 and several DomU (centOS, Debian and
