Hello, I just setup a few virtual systems, and I came into some limitations using XEN. I''d like to share these, just to know if the limitations are in the system or in the user :) I am using a standard Debian 4.0 (etch) GNU/Linux distribiution. The system is an Intel Core 2 duo with virtualization inside. I use the amd64 flavour. Thus my kernel is

Hello all, I have a PowerEdge 2950 that I am using to host Windows XP VM's under CentOS. I am experiencing poor performance in the Xen VM's. Any time I try to do something, the CPU usage (as reported by the Windows task manager) hits 100% for a few and then drops back down. This is causing the VM's to run sluggish and be quite annoying to use. Example.. I click IE.. cpu hits

Hello all! We are testing virtualization with two Sun X2200 M2 (2 x Opteron Dual Core) with Xen (3.1.3, locally compiled, Debian etch), KVM (Debian Sid) and Windows Virtual Server (Windows 2003 Server). We have tried paravirtualization and also full virtualization (Pacifica). In all cases we have experienced problems regarding stability in the systems, specifically erratic lost of network

So, as promised, here an first summary. Hardware: AMD Athlon64 X2-4600+ with Asus M2N-Mainboard. Just a short hint: By far not all memory modules work with the Asus boards! Make sure to have compatible ones... After 2 days of trial and error I got the following results: Debian "Sarge" x64: Doesn''t like the new nVidia SATA-Controller (will check today with PATA-interface)

Hello, I have some questions about Windows virtuzalisation on XEN. I currently ran some test on Windows'' VM (Server 2003 mostly) for my job. But I can''t make some of my expectations which could be useful for my prod environment. Here are my questions: - Is it possible to have more than 2048Mo of memory per Windows VM with a 32bits CPU ? - Is it possible to have multiple CPU

Hello, Is it reasonable for one CPU on the host to be loaded 20-30% on 100 mbps download in a guest? There is barely any (1-2%) load in the guest. The host is running ubuntu 18.04 on an Intel i7-7700K, virtualization etc is enabled. Everything except host load on guest network activity is fine. This is how i setup the network with virt-install: --network

Hi, I am running CentOS 5.3 32bit as a VirtualBox 3.0.0 guest running on Windows XP. The Windows host CPU usage is constantly at 50% although the CentOS guest is completely idle (i.e. 0.00 load average). I know this is a common problem related to the 1000Hz frequency that the CentOS kernel runs at. With previous versions of CentOS, I used the kernel-vm package [1] and it solved my problem.

Hi I''ve been running xen with linux guests for a while now and thought I''d try windows as I have a new server. All seemed to go fine except performance is *horrible* - I''m currently installing Win2003 SP2 and it''s been running over 12 hours (thank god for vnc) - each individual file is taking between 3 and 4 seconds each. Server is an intel E6600 with

I am trying to setup Xen virtual servers using a Debian etch with the xen 3.0.3 provided in 32 bits mode. I am using full virtualization. I managed to get things started using the configuration provided below. I was able to run the install (with boot="d"). I even managed to start the system afterwards, and it runs correctly. But now I encounter a problem I already hit when running

hi all, i have a strange behavior on opensuse 10.2 GM. kernel-xen-2.6.18.2-34 xen-3.0.3_11774-20 when i try to setup a fullvirtualized xen instance, the vm crashes randomly during installation. i found out, that always before the crashes my X Server Screen gets corrupted a little bit. i switched to runlevel 3 and tried again and everthing worked. to make sure that it wasn''t luck, i

Hi all! I have recently purchased an Athlon X2 3800+ and I should like to install FreeBSD or OpenBSD in a HVM domU on Xen 3.0.3-1 dom0 (Debian packages). Is it possible? In such case, can someone recommend me a guide/howto to accomplish it? Thanks in advance.

Hi, It seems to be a very basic question, but need confirmation. I am using Centos as my Dom0, running xen, using paravirtualization.

Hallo! I am using on a system based on Debian GNU/Linux Etch on AMD64 platform Linux and Solaris running in a HVM domU but they both seem to be 32bit environments. I know so because 64bit Linux didnt boot and said something about am I trying to run it in 32 bit environment; and because i had to install 32bit Oracle because 64bit Oracle said it expected BIT_SIZE=64 and got BIT_SIZE=32. And also,

Windows 2k8 R2 guest with updated virtio drivers is idle inside but on the host qemu-kvm process uses 7-15% cpu. Things that have been tried without any significant success - removed tablet device - manually set cpu topology for cores per socket Is it just me or the qemu-kvm has little tolerance with windows?

Hello all, I am fairly new to Linux, so I hope that the following problem is not just me being ... new to Linux. I have been trying to install Wine on Debian (Etch 4.09 I think it is called). I first tried to use the apt-get install Wine command followed by the winecfg (creating the .wine folder), but when I tried to run the notepad.exe (i.e. with the command wine
