Hello, I am still confused: does pyGrub run in dom0 as root? as it says in here: "PyGRUB used to act as a “PV bootloader”: it runs in dom0 as root, opens the PV disk image, reads its GRUB menu.lst, presents a GRUB-like menu to let the user choose a kernel which it copies to the dom0 filesystem, it then closes the disk image and eventually tells the domain builder to use that copy. Such a

Hello, I am still learning about Xen.. I am trying to setup Xen hypervisor for the first time. I was reading the howto here: http://www.howtoforge.com/paravirtualization-with-xen-4.0-on-debian-squeeze-amd64 and I stopped here: "(To use the default Ubuntu kernel instead of Debian''s Xen kernel in the guest, you can also comment out the kernel and initrd lines in

The mystery gets more interesting... I now have a CentOS 7.3 Dell R710 server doing the exact same thing of rebooting immediately after the Xen kernel load. Just to note this is a second system and not just the first system with an update. I hope I'm not introducing something odd. They only "interesting" thing I have done for historical reasons is to change the following

Hello! Trying to find out some guides how to set up freebsd under xen, all i found is pointing to www.fsmware.com, <http://www.fsmware.com/xenofreebsd/7.0/download/> which is down!

Hi, We were hoping to attend an IRC meeting this morning but it looks like that didn't happen. Has this been moved to once a month or was this a special week? Thanks, Sarah

(I posted this on xen-users last week, and nobody seemed to know what was up. It is time, I suppose then, to dust off the debugger; I was hoping one of you could point me in the correct direction to begin troubleshooting this.) I''m HVM booting our install-disks (systemimager) here, and I''m spotting some weird performance issues. Our install uses rsync and prints every

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah

Hello, I have Xen running on an Ubuntu 8.04 LTS machine. This machine has been in production for a few months now. Up until recently, all the DomU machines have also been Ubuntu 8.04 machines. Recently, I tried creating a Debian Lenny machine. I use xen tools to create the DomU machines. Upon completion of creating the DomU with xen tools, I start the DomU using the [sanitized] command

Hello, Given that nowadays standard Dual Quad Core server is such popular, with Dual GB Ethernet, bundles of high capacity of SATA disks running as RAID 10. What are the factors that prevent you from installing additional VM on an existing server? e.g. 1. CPU 2. Memory 3. Disk I/O 4. Network 5. Else? _______________________________________________ Xen-users mailing list

Hi. This is mostly hypothetical, just because I want to see how knowledgeable people would go about achieving it: I want to sandbox Mozilla Firefox. For the sake of example, I'm running it under my own user account. The idea is that it should be allowed to connect to the X server, it should be allowed to write to ~/.mozilla and /tmp. I expect some configurations would want access to audio
