Might want to give PCI latency setting a try, it helped for me. My ZTTEST would drop occasionally to 99.95% until I set: setpci -v -s 01:01.0 latency_timer=ff

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

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.

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

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
