Hi All, I have working CentOS xen guest (domU) inside in Debian xen domain (dom0) and here is the domU''s config file <http://fpaste.org/paste/7295>. How could I put the proper syntax inside of domU''s config to instruct the domU to boot the /data/CentOS-5.1-i386-bin-DVD.iso during starting of domU? BTW, I am using xen-3.2-1. Thanks, James

Hi, I''m just wondering if there are any speed or stability differences between running a system directly of a LVM partition versus a xvd partition? Basicly: disk = [ ''phy:/dev/LVM/root,xvda,w'', ] vs disk= [ ''phy:LVM/root,hda1,w'',] Any tips? I tried searching the archives but I didn''t find anything. Kind regards, Tarjei

Hi, How to boot the centos dvd image (/download/centos/centos5.2.iso) in xen guest system to let me do linux rescue command?

You get these if you install Debian Wheezy as HVM and then try to convert to PV. This is Debian bug #603391.

I am running Xen 4 and want users to be able to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s

Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

Hi, I''m running CentOS guest domU under Debian dom0. I''m planning to install Xorg to run GUI in CentOS guest for testing only. How could I tell the CentOS guest domU to display the GUI in my VNC client in which I''m remoting from outside on internet? Let say I''m connecting from my home to the xen guest located in office. Hope someone could help me on this.

Hi! Say I export an LVM logical volume from dom0 as /dev/xvda to the domU: disk = [ ''phy:xenimages/stan,xvda,w'' ] No I can lvresize xenimages/stan in dom0, but the domU stays ignorant of this change. How could I propagate the resize to the domU without rebooting or temporarily breaking its connection to /dev/xvda? Sort of a SCSI rescan, perhaps? -- Thanks, Feri.

Is there anyway to get gigabit networking for a fully virtualized guest? I''ve tried searching for this one, but all I get are results about gigabit networking for the host / dom0, nothing for domU.

Hi have 4 dom0 with debian lenny running xen. When I run ps axf|grep xvd I see it''s different on diferent dom0s. dom0-A 15677 ? S< 0:00 \_ [blkback.139.xvd] 15678 ?

LANANA has officially assigned the block major of 202 for xvd devices (http://www.lanana.org/docs/device-list/devices-2.6+.txt). Take advantage of knowing this so people don''t have to do the mknod on their system. Also, fix up the scsi regex to get sda correct without having to do hacks like sda0.

Hi Everyone, When you want to use ionice to limit the amount of disk a DomU has, due to have to run ionice on every blkback process? Incidently, what is the format of the blkback process? I see the following in ps aux: blkback.xx.xvda blkback.xx.xvda1 blkback.xx.xvd where xx appears to be the domain ID. I''m curious as to the last few letters mean? Thanks

Confirmed this issue. To reproduce: Install a fresh Wheezy AMD64 guest under Xen 4.1 (hypervirtualized, boot from the debian-7.1.0-amd64-CD-1.iso). Use "entire disk" automatic layout for partitioning, this creates /dev/xvda1 for / and /dev/xvda5 for swap. It will create /boot/grub/grub.cfg with many references to (/dev/xvda,msdos1) which works fine when the machine is booted

centos-virt, I'm trying to create/install domU guests all in "one" step, following Daniel's wiki page (I've found these pages really helpful, BTW): http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU I have a few questions about this process: (1) How would it be modified (w/respect to defining the disk in the domain configuration file) to use a disk layout where dom0

Hi,All, I installed a guest os with full-virtualization and a local volume as the disk, now becuase of poor performance, I want to change the full-virtualization guest to para-virtualization, so I just changed the config file to boot the guest os with para-virtualization, but it fails to boot. but how can I convert the full-virtualization guest to para-virtualization without reinstall the os,on

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and
