Re: [Fedora-xen] Unable to use multiple CPUs inside an HVM
I have noticed that too.

Both xm and virsh show that the guest only has 1 CPU, but my config file and the guest show it should have 2. What am I missing? How can I get this guest to have access to both cores? Thanks!

Re: [Fedora-xen] Freeze with xen is relinquishing vga console
Fedora9 does not work as a XEN Host (Dom0). I read that it will be back in Fedora10. I sure would help if this was clearly specified in the Fedora9 wiki.

Well, I suspect your disk parameters are simply wrong...
disk =
['phy:vg_virtual/lv_myzel_root,sda1,w','phy:vg_virtual/lv_myzel_swap,sda2,w']
-This one seems to be messing / or /dev before vg_virtual.
disk = ['tap:aio:/virtual/centos.5-1.64.img,sda1,w',
'tap:aio:/virtual/centos.swap,sda2,w']
-This one I'm not sure, but I use file:/, have you tried it like below?
disk = ['file:/virtual/centos.5-1.64.img,sda1,w',

Re[2]: [Fedora-xen] no sda1 in DomU
hi,
II create a initrd with xenblk module
big thanks for the hint - I created the initrd by using

--omit-raid-modules --omit-lvm-modules --omit-scsi-modules
/boot/initrd-2.6.18.xenU.img `uname -r`
the VM boots now, but hangs after starting the crond:

also, although the network is configured properly, the interface can't

a xm shutdown myzel shuts down the VM properly (vm console shows

do I need to put any additional modules into the initrd ?
tnx in advance.

Re[2]: [Fedora-xen] no sda1 in DomU
II boot in single user mode, start network and update your linux with yum ok, I'm now one step further: - can boot into single user mode - all block devices are mounted in the VM - network starts properly, yum update loaded applied some updates - sshd starts, I can ssh into the vm from outside. dmesg shows some strange messages: XENBUS: Device with no driver: device/vbd/2049 XENBUS: Device with no driver: device/vbd/2050 XENBUS: Device with no driver: device/vif/0 Floppy drive(s): fd0 is unknown type 15 (usb?), fd1 is unknown type 15 (usb?) Failed to obtain physical IRQ 6 floppy0: no floppy controllers found lp: driver loaded but no devices found my assumption: the VM can't connect to the console or some tty or whatever because of the missing drivers what means that the login prompt doesn't show. I exaleaded for the messages and found some threads with the same problem, but without solution: http://www.mail-archive.com/fedora-xen@redhat.com/msg00076.html http://lists.xensource.com/archives/html/xen-users/2006-08/msg00064.html II Rainer Fuegenstein wrote: hi, II create a initrd with xenblk module big thanks for the hint - I created the initrd by using mkinitrd -v -f --preload=ext3 --preload=xenblk --preload=xennet --omit-raid-modules --omit-lvm-modules --omit-scsi-modules /boot/initrd-2.6.18.xenU.img `uname -r` the VM boots now, but hangs after starting the crond: [...] Press 'I' to enter interactive startup.
