Dotaz: problem spustit xen guest

[moky]

Dobry den,

mam nasledujuci problem so xenom. Pri spusteni:

 xm create -c  /etc/xen/xmwebserver.hvm vmid=1

dostanem:

pre uplnost som sem dal cely vypis. OS je Fedora 8. Xen som instaloval prostrednictvom yum.

pricom v md3 je este spraveny lvm. Myslienka bola taka, ze prave v tomto lvm bude fungovat xen. Je tam teda particia /dev/vg/domu1 (120G) + /dev/vg/domu1.swap (2GB)

konfigurak toho xenu je:

Googlujem uz tyzden, a su rozne veci. Najpravdepodobnejsie je,ze mam nespravne spraveny initrd a preto som skusal aj toto:

mkinitrd --omit-scsi-modules --with=xennet --with=xenblk --preload=xenblk initrd-$(uname -r)-no-scsi.img $(uname -r)

a vysledok bol uplne rovnaky

Neviem si s tym rady, pls. help.

dakujem

odpoviem si sam. :) tak sa to podarilo vyriesit. V konfiguraku xenu /etc/xen/xenexample.hvm treba mat:

disk = [ 'phy:/dev/vg/dom1,sda1,w' , 'phy:/dev/cdrom,hdc:cdrom,r' ]
root = "/dev/sda1 ro"

teda ziadne ioemu..

dalej na

mount -o loop /dev/vg/dom1 /mnt

potom zmenit v /mnt/etc/fstab

/dev/sda1                /                       ext3    defaults        1 1

nakoniec samozrejme

umount /mnt
