xen-create-image does not create inird or initramfs image and domU does not starts with system image
- by user219372
I have Fedora 19 as Dom0. To create image I run
# xen-create-image --hostname=debian-wheezy --memory=512Mb --dhcp --size=20Gb --swap=512Mb --dir=/xen --arch=amd64 --dist=wheezy
After generation finished I start vm and see:
# xl create /etc/xen/debian-wheezy.cfg
Parsing config from /etc/xen/debian-wheezy.cfg
libxl: error: libxl_dom.c:409:libxl__build_pv: xc_dom_ramdisk_file failed: No such file or directory
libxl: error: libxl_create.c:919:domcreate_rebuild_done: cannot (re-)build domain: -3
In the /etc/xen/debian-wheezy.cfg i have
#
# Kernel + memory size
#
kernel = '/boot/vmlinuz-3.11.2-201.fc19.x86_64'
ramdisk = '/boot/initrd.img-3.11.2-201.fc19.x86_64'
and ls -1 /boot/*201* shows
/boot/config-3.11.2-201.fc19.x86_64
/boot/initramfs-3.11.2-201.fc19.x86_64.img
/boot/System.map-3.11.2-201.fc19.x86_64
/boot/vmlinuz-3.11.2-201.fc19.x86_64
Then if I fix ramdisk directive in .cfg file to /boot/initramfs-3.11.2-201.fc19.x86_64.img vm will start but os inside will not boot. In a tail of xl console I get
[ OK ] Reached target Basic System.

dracut:/#
.img files in /xen/domains/debian-wheezy exists and listed in disk section of debian-wheezy.cfg
So what should i do?
Update:
I've found that xl does not mount images. In debian-wheezy.cfg I have that:
root = '/dev/xvda2 ro'
disk = [
'file:/xen/domains/debian-wheezy/disk.img,xvda2,w',
'file:/xen/domains/debian-wheeze/swap.img,xvda1,w',
]
And there is no /dev/xvda* or /dev/sda* or /dev/hda* files in VM.
