I tried to use cdrom in domU linux pv (Linux Mint 11 based on Natty). With ''/mnt/vm/iso/test.iso,raw,xvdb,ro,cdrom'', Mint sees it as internal disk (not cdrom) and only administrators can mount it. I tried also ''/dev/scd0,raw,xvdb,ro,cdrom'' does the same thing. Is possible use cdrom on linux domU pv full working where also normal user can mount it without terminal? Did I somet...

Hello, I just installed Xen 4.0.1 on Ubuntu 10.04 dom0. After this i had Ubuntu 11.04 as Para domU. I tried to attach file based disk to the this domU. My command is: # xm block-attach Ubuntu-11 file:/root/ubunut-natty/Extra /dev/xvdb w there is no error on this. But inside the DomU i cannot see any disk xvdb. xend.log shows : [2011-10-25 16:27:32 14794] DEBUG (XendDomainInfo:853) XendDomainInfo.device_create: {''uuid'': ''18743cdb-d88a-84e3-c2e4-c5c726e06cda'', ''bootable'':...

...filesystems through blktap2 here is how you do it, as I couldn''t find it fully documented. The instructions on the blktap2 readme file are rather out of date. You can mount them under Dom0 like so. e.g. to mount a vhd file, sudo xm block-attach 0 tap2:vhd:/home/xen/xenwin7-persist.vhd xvdb w 0 Now the device should appear under /dev ls /dev/xvdb* /dev/xvdb /dev/xvdb1 /dev/xvdb2 sudo mount /dev/xvdb2 /mnt Mounts the first partition on xvdb to the path /mnt

...ce to a VM. type: VBD ref: 66b1f602-fe0b-f4f7-ba41-47c7f7e01dea The VBD in question is for a VDI that exists on a Local disk SR of type ''ext'' (i.e. mounted ext3 disk). The SR is attached and mounted, and everything seems OK there. After the command, there''s a ''xvdb'' device that shows up in dom0, which seems to indicate that the attach was successful (at least at the low level, even if not within xapi): [root@localhost ~]# ls -l /dev/xvdb brw-r----- 1 root disk 202, 16 Apr 15 13:45 /dev/xvdb And tap-ctl lists the attached data disk: [root@localhost...

My assumption here is that the <vdb_num> given to the -v option translates into /dev/xvda for -v0, /dev/xvdb for -v1, etc. Is that correct? BTW, do I need to create a distinct virtual device which grants access to the domain whose kernel is going to use the virtual disk as its root? Currently I do not, I just set root=/dev/xvdN in xi_build where xvdN is the device I create/use here for dom0 initializati...

Hi, for hours now, I am trying to upgrade a paravirtualized Opensuse 10.3 to 11.0. I turned it into a hvm machine, set boot="d", but I cannot get it to work. file:/os-images/opensuse_11.0_32bit.iso,xvdb:cdrom,r results in Booting from CD-Rom... CDROM boot failure code : 0002 Boot from CD-Rom failed: could not read the boot disk FATAL: No bootable device. If I change xvdb to hdc, Suse''s splash screen comes up, but without any feedback, just a green screen with the Suse logo, nothing else...

...trying to set up Xen paravirt guests with access to 2 block devices: One for / and one for swap. The block devices are LVM LVs, but that shouldn't matter. When I create the guest using either virt-manager or virt-install, I get asked which device to use for xvda. But I want more block devices: xvdb for swap. I know how to add this as an option to the config file in /etc/xen 'phy:/dev/vg1/guest1-swap,xvdb,w' But that file only appears AFTER running the installer. How do I make xvdb visible DURING the install of CentOS? Thanks, -- Francois Caen

Hi, folks, I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)
