ACPI HPET Timer - Works on standard Kernel - Broken on Xen Kernel
I have an error in my dmesg system log about hpet not correctly enabling: hpet_acpi_add: no address or irqs in _CRS The same kernel without Xen enables it fine: hpet0: at MMIO 0xfed00000 (virtual 0xffffffffff5fe000), IRQs 2, 8, 31 hpet0: 3 32-bit timers, 25000000 Hz hpet_resources: 0xfed00000 is busy Do I have to pass an additional boot option?

Linux PV Drivers - VBD device not loading - Cannot get Major 3/22 for ide
I am trying to get PV drivers running on both Centos 5.1 and Centos 5.3 HVMs, my DomU is Centos 5.2 with Xen 3.31. For 5.1 I install the kmod-xenpv RPM but for 5.3 the drivers seem to be built-in. For the network drivers to work I had to unload the Realtek NIC driver and renamed its .ko files to stop it loading. Adding the Xen-Vnif alias to modprobe.conf then got the PV NICs working nicely (Much

RE: xen - rdma live migration support
Hi Ola, There was some code done by IBM a few years ago in conjunction with a University that worked and showed the benefits but AFAIK it was never integrated into Xen. The research paper is around on the web. A few of us requested RDMA migration support for version 4.0 and it is at the top of the request list, I suspect it is probably a case of enough people asking and Citrix approving.

NIC Offloading Confusion
I have been using the built in Xen Paravirt NIC drivers for paravirt networking and had bad performance until I disabled all offload setting on the bridge and paravirt nic (From Dom0). There are 2 related questions I have, where should I be tweaking the offload settings, the Dom0 Physical NIC, The Bridge or the DomU NIC? Which settings in particular tend to cause trouble?

write geotiff with projection - RGDAL package
Hi, Doing more search i've discovered package RGDAL that can write a geotiff file with projection. I saved a geotiff file in UTM projection and if i read the file back in R and check the projection seems that everything is OK. But if i load the file in ArcGIS (ESRI product) i get the warning that the file is missing spatial reference so it cannot be projected, but it is displayed correctly.

Trusted certificate for Encrypted VNC + Vencrypt
I was wondering if anyone has managed to get a trusted certificated to work with Xen''s Encrypted VNC and Vencrypt? I can generate my own cert with Certtool and this works but as expected I get warnings from Vencrypt: "Certificate Issuer Unknown" "Certificate Not Trusted" "Hostname Mismatch" After some time working with my Cert provider I have a CA signed

RE: [ofa-general] Infiniband performance
Hi Jan, I asked almost the exact same question as you about 6 months ago and someone provided some Gen4 results for me (But I can''t seem to find them in email), they were a fair bit better than Gen3. With IPOIB, you want connected mode and a large 32Kb+ MTU for max bandwidth, 1Gbyte/sec or more should be possible with Gen 4. Here are some of my original test results on my Opteron

3.2.1+ HVM + HAP + NUMA - Poor Memory Performance
Hi Everyone, I am running 3.2.1 on Centos 5.2 with HAP enabled, NUMA enabled, ACPI enabled and the dom0 allocated 512Mb.

Xen PV 0.9.12-pre3 with Multiple NICs/Bridges, Hard Lock
Hi Everyone, I''m using a Xen 3.30 on Centos Dom0 setup with two bridges, one for WAN and One for LAN (Both are on separate physical NICs within Dom0). I can use a 2 NIC setup with Server 2003 Pure HVM fine. A single NIC setup works fine with the Pre3 drivers but as soon as I add the second NIC the system hard locks within a few seconds of networking coming up. Both NICs looks fine from

Xen 3.3.0 cpu cache problems
Dear Xen users, I have a problem with "Xen 3.3.0". All domU (paravirt) only have "32 KB" of cache instead of "6144 KB" as listed in dom0. This is really noticeable under load since the system tends to be really slow. I did not have this problem with "Xen 3.2.1". I''m using the same domU configuration files for the new and the old installation.

Centos 5.2 using LVM -> DRBD 0.82 -> Xen Problems

I''m pretty sure my xen config file is OK and the DRBD device looks fine too. Full details below. xm create centostest Using config file "./centostest".
