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? (ACPI is already enabled) or is there

Hello All, Does anyone know what is the current status of RHEL 5.2 x86_64 with respect to the maximum amount of RAM detected by the Xen 64 bit kernel (the one that shipped with Red Hat distribution ) In the following link https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/en-US/RHEL510/Virtualization_Guide/ch-virt-hw-support.html it states that 32GB of RAM is the maximum amount of

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated: Each Node: Dell R210 Intel X3430 Quad Core 8GB RAM Intel PT 1Gbps Server Dual Port NIC using linux "bonding" Small pair of HDDs for OS (Probably in RAID1) Each node will run about 10 - 15 customer guests Storage Server: Some Intel Quad Core Chip 2GB RAM (Maybe more?)

Hello list; I´ve updated my windows 2k3 GPLPV drivers from 0.9.9 to 0.9.12-pre13. But now, i have two xen block devices; (of course, one of them is not working and is marked with the yellow exclamation). How can i fix it, or how can i uninstall the GPLPV drivers in order to make a clean install? Thanks Juan Pablo _______________________________________________ Xen-users mailing list

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? (I just disabled all of

Sorry to have so many questions but I seem to have quite a few mini problems with my first Xen setup. My xen server works fine with Powernow on the standard Kernel but with the Xen kernel it fails. Does anyone know why? Details below. With Standard Kernel powernow-k8: Found 2 Quad-Core AMD Opteron(tm) Processor 8350 processors (8 cpu cores) (version 2.20.00) powernow-k8: 0 : fid 0x0

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.

The subject says it all really, I''m pretty sure the system and bios are NUMA aware but I''m not sure if it''s enabled? Is it supported in 3.2.1 stable?

Hi, I would like to ask the proper or recommended way of upgrading xen...? I started with 3.1.0 then upgraded to 3.2.1 but now I am not able to use the original system. Since I am not satisfied[*] with the current setup I would try to upgrade to 3.3.1 but it would be nice if something went wrong I could downgrade it to 3.2.x... It is a pitty that booting the previous xen image does not work

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

i''m reading up on numa usage. so far, i''ve enabled numa on my Xen box. @ Dom0 i see, xm dmesg | grep -i numa (XEN) Command line: ... numa=on ... (XEN) No NUMA configuration found i guess i need to ''configure'' numa. i''ve no clue how, and haven''t found the docs for it yet, despite looking. i found this old thread,

Hi everyone, This is my first attempt at a PV guest install from scratch and I''m a tad confused. Have I answered one of the questions virsh-install asks wrongly? Does anyone know of a general guide for installing PV guests with virsh-install? (Most Centos docs seem to use the GUI based virt-manager and I only have command line access). Am I meant to make use of the files here:

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

Hello, I am trying to install Win2008 x64 on xen. However it always crashes with: 0x0000005b which from my research means incompatible CPU. Can anyone assist with this?

Hi, we''re contemplating getting a large new server, where we will run a number of virtual servers. Are there any things we need to keep in mind in that case? Are there limitations on what a Xen system can manage? We''re talking about a 4 x Quad core CPU server with 64 GBs of RAM and a couple of terabytes of RAIDed SATA storage. -Morten (Re-sending this, as the first message

Hi Everyone, I''m trying to get Xen to use a native DRBD device but it seems it will not create the virtual machine. It does not seem to like the DRBD device type, any ideas on what might be wrong? 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".

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

Hi Everyone, I am running 3.2.1 on Centos 5.2 with HAP enabled, NUMA enabled, ACPI enabled and the dom0 allocated 512Mb.
