similar to: xen 4.0.1 from source on Debian Squeeze grub2

Hi! I''m experimenting with Xen 4 on Squeeze. Squeeze uses grub2 by default, and the config format has changed. I can''t for the life of me figure out where to set options for the hypervisor and the Dom0 kernel on bootup. It seems the grub2 stanza for xen is being generated by /etc/grub.d/20_linux_xen and that seems to have some provisions for receiving arguments, but I

Hey all, I have moved 10_Linux to 50_Linux and ran update-grub which is fine. The problem I have is that there is xen-syms in /boot And that is being put first in the boot list which is incorrect. How do you make /xen.gz at the top so it is booted first? Thanks Ian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi guys, Having a weird issue with a Dom0. When we were running 2.6.18.8 kernel the server would lock up every 2 weeks for no reason. Its been a difficult one to resolve as there are no errors. We have now upgraded to 2.6.32.13 and the lock ups are more often. For example today it crashed in the morning, then it was rebooted and it crashed again about 5 hours later, no logs. The

Hello, I''m struggling to handle the amount of memory that dom0 gets on some system. It''s a system with 8GB of RAM, running 2.6.38-6 with pv_ops and Xen 4.1 If I want to set the amount of memory for dom0, I get very bogus results. See here: http://pastebin.com/gRgY9ERN If I use the M notation (xl mem-set 0 4096M) the outcome is similarily unpredictable, and sometimes I get the

If this has already been done, please forgive me. However, if not, I''d like to submit this as a mechanism for generating a bootable grub2 stanza for hypervisors. As the /etc/grub.d/* files rely on defaults in /etc/default/grub, I added the following Xen specific variable: GRUB_CMDLINE_XEN_DEFAULT="console=com1 115200,8n1 dom0_mem=512M dom0_max_vcpus=1 dom0_vcpus_pin=true

Dear All I am using Centos 7 with Xen 4.6 on a Dell Poweredge T430 When the machine boots, after the 'Scrubbing Free RAM' message, I get a screen filled with little white squares until the login prompt, so I cannot see what is happening as the machine boots. Also there is nothing on the screen when I reboot. My /etc/default/grub is GRUB_DISTRIBUTOR="$(sed 's, release

Good evening everyone, I am attempting to compile Xen 4.2.1 from source on Ubuntu 12.10 and cannot for the life of me figure out what I am doing wrong. This is the script I wrote that I am running on a brand new install from ubuntu-12.10-server-amd64.iso apt-get update apt-get -y upgrade apt-get -y dist-upgrade reboot (uname -r returns back 3.5.0-23-generic) apt-get install -y build-essential

Hi all, Recently I build XEN 4.1 (from the xen.org) on centIOS 5.5 (kernel 2.6.38.4). After changing the grub file and rebooting the machine, I am continuously getting out of memory error.

Dear George, Thanks for the input and ideas. Unfortunately bootscrub=false dos not work, not does setting nothing for vga, still get the 'Little white squares'!

Hi, I''m trying to figure out how XEN decides which VNC port a particular VM will associate with. From what little there is in the documentation, it indicates that XEN will choose 5900+DomainID. From experience, this doesn''e seem to happen. When I start a guest domain, and do "xm list" its domainID shows as "22", however, when I netstat -a , it shows listening

Hi Everyone I have sorted out the initial issues I''ve had and decided to give Xen another go. I''m trying to run Xen using kernel 2.6.37-rc3 (previous attempt with rc1 failed, and when I gave it a second go, rc3 was already out). As previously, 2.6.37-rc3 boots fine natively. 2.6.32 boots natively and under Xen as dom0, but I have reservations against running 2.6.32,

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

Hi, Ive built a new server using xen debian lenny packages. Im trying to firewall dom 0 which i can do ok but it then blocks access to the dom Us. Has anyone managed to do this successfully?

Further to my messages back in May I have at last got round to trying to get my DomU to recognise USB devices. I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64. I have to manually make the port available before creating the DomU by issuing the command: xl pci-assignable-add 00:1a.0 otherwise nothing shows in: xl pci-assignable-list I have added this to my .cfg file as per the

Hi, Having a problem getting a domu to boot correctly. When I enter xl create guest it boots straight into grubdom. If I enter the config location in grubdom t boots as expected. The location of the grub.cfg is the same in my domu config as what in entering but just will not work. Any ideas? Ian .
