Hi list, I recently installed the Trixbox distribution as an HVM and have now converted it to a PVM. Found very few resources on Internet where people had done this conversion so I had very little to compare with. Wanted to ask for comments about the kernel used in the PVM after the conversion. Installing Trixbox and later installing the xenified kernel, gives a kernel of 2.6.18-92..... In my

I am using xencenter to connect to my ubuntu 12.04 xen box If i create a PVM with a template, everything works great if i create a HVM with the custom template, the console does not respond to keyboard or mouse clicks? any ideas what could be the problem? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Thanks you all guys. I am able to create the RHEL5 PVM on RHEL5 host successfully. Only thing that i need to add is /mnt/etc/fstab in inintrd command and preload to both the fronthend drivers. As blow. # mount /home/disk /mnt # mkinirtd /boot//boot/initrd-2.6.18-8.el5xenU.img 2.6.18-8.el5xen --fstab /mnt/ etc/fstab --with xenblk --with xennet --preload xenblk --preload xennet Thanks a lot,

Hello R enthusiasts, I am working with a Fedora Core 6 OS and R 2.5. I have just finished loading PVM on my test cluster and this is working properly. Also, rpvm has been loaded in R. However, when I try to load my test program, I receive this error: Loading required package: rpvm Error in dyn.load(x, as.logical(local), as.logical(now)) ; unable to load shared library

(My apologies if this is the wrong list or if this question has been asked before. I’ve done quite a bit of searching and can’t find an answer) I am working on a heavily modified version of CentOS with a user-land that mostly matches 5.4 and a kernel based on 6.2. I''ve found tutorials on how to create a CentOS PVM (such as http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU) but I

Hi, I tell you my problem: I've installed a Ubuntu's HVM guest in CentOS with XEN, then I convert my HVM to PVM based in this tutto : http://www.asplund.nu/xencluster/xen-convert-hvm-to-pvm.html After this modification everythings it runs fine but I have a problem with xconsole, I don't see anything when I run the command "xm console ID" , I only see the boot proccess and the

What is the best practice in creating PVm domU''s - with or without swap? >From the admin point of view, especially in HA environment it is temptating not to have a seperate swap partition. Could it be performance issue if swapping to swap-file insted of swap-partition? What about pure swapless- no swapfile, no swap-partition? Any expirence out there? regards Longina -- --

I''m trying to do nested XEN to give some of my colleagues a play area to work in, and it seems to work - but not quite. I can build the nested environment (using OVM, and I have to step back to OVM3.2.2 to allow me to do PCI passthrough), but as soon as I start up a VM with a phys device passed through, the first layer loses all connectivity to the SAN. Setup: * 2 UCS

Hi All - I'm running a faily long script that uses rpvm & snowFT to spawn off multiple processes with the 'clusterApplyFT' function. Specifically, what happens is that the head node generates a number of seed clusters that are then spawned off to the pvm cluster (in this case, nodes on a 4 dual-core machine) using clusterApplyFT to apply a function to each seed cluster that

Hi Xenners, I have tried to upgrade to kernel 3.5 and experienced the USB/PCI passthrough problem. This has not been "fixed" in 3.6 either. I do not know if this is qemu, xen or kernel related. I am using Xen 4.2 final and Xen 4.3-unstable to test. DomU is Windows 7 64 bit or Linux Fedora 17. In Windows, I get the little yellow triangle with Code 10 (I know this means nothing...

I''m going to set up a PVM on xen-3.3.1 debian-amd64. I need advices about the best methods to install a fresh debian on it (i.e. how to choose the kernel for pvm) . I''ve installed xen from sources and only have one xen kernel in /boot which I''m using for dom0; should I use the same kernel for domUs? There is any problem on use vcpus=2; the other vm is an hvm running

Hello, all. I''d like to get some feedback on why Linux support for Xen environments is (seemingly) poor, compared to other virtualisation software. I do a lot of testing of different types of VMs; firewalls, SMB servers, etc. and find myself increasingly frustrated that, though most of these systems I test run Linux almost exclusively, the vast majority have no Xen support.

I have a kickstart file created that works great for installing CentOS on PVM''s and now I want to use it for HVM''s as well. The problem is that when I attempt to run the install, it seems to ignore the kickstart and starts prompting me for all the things I already have specified in the kickstart. Any idea what I could be doing wrong? Here is the command im using to get things

I am new to Xen and want to provide simple communication between my DomU and Dom0 environments. I just need to be able to pass a few bytes of information back and forth between DomU and Dom0 while using some form of event management to know when an update occurs so I can act on it. At first, it appeared that using XenBus and XenStore might be the right solution for this. However, after looking

to convert hvm to pv guest, I have followed the direction( link<http://pastebin.com/f6a5022bf>) in Xen-Users Common Questions Guide. It says the first step is "install kernel-xen with correct initrd" After "yum install kernel-xen" was executed, following errors were showed: WARNING: No module xen_vbd found for kernel 2.6.18-164.15.1.el5xen, continuing anyway grubby

Hi all! I am running SXCE 121 on a dual quad-core X2200M2 (64 bit of course). During an installation of a NetBSD 5.0.1 PVM domU, the entire machine crashed with a kernel panic.

Dear Friends, I'm trying to learn to use parallel computation using snow & rpvm Now, I have two boxes: 1) Pentium 4, pvm 3.4.5, R 2.2.0 with FreeBSD 5.4 (box uffbsd); 2) PowerPC, pvm 3.4.5, R 2.1.1 with Debian Linux latest stable (box powerpclinux); I'm using the instructions in (found in snow.pdf) http://www.stat.uiowa. edu/~luke/R/cluster/cluster.html.
