Xen PARAvirtualizacja - boot loader didn't return any data

Witam. Pod Xen3 (CentOS5  AMD PhenomII X2 64)  zainstalowałem bez problemu Debiana6 w trybie pełnej sprzętowej wirtualizacji HVM (kernel 2.6.32-5-xen-amd64)
Na bazie tej instalacji chciałem tę instalkę uruchomić w PARA wirtualizacjil, zmieniając jedynie plik konfiguracyjny xena na PV:

Kod:

name = "Debian-6.0-amd-64-fullvirt"
uuid = "12e8fb62-23c0-5e84-2979-645e05b2df50"
maxmem = 1212
memory = 512
vcpus = 2
#PV - para wirt
bootloader = "/usr/bin/pygrub"

#HVM - pełna wirt
#builder = "hvm"
#kernel = "/usr/lib/xen/boot/hvmloader"
#boot = "c"
#pae = 1
#acpi = 1
#apic = 1
#sdl = 0
vnc = 1
vncunused = 1
#keymap = "pl"
localtime = 0
on_poweroff = "destroy"
on_reboot = "destroy"
on_crash = "destroy"
device_model = "/usr/lib64/xen/bin/qemu-dm"

disk = [ "file:/var/lib/xen/images/Debian-6.0-amd-64-fullvirt.img,hda,w", "file:/home/andy/Desktop/XEN/iso SO/debian-6.0.1a-amd64-DVD-1.iso,hdc:cdrom,r" ]
vif = [ "mac=00:16:36:4a:e0:87,bridge=xenbr0,script=vif-bridge,vifname=vif15.0" ]
parallel = "none"
serial = "pty"

Jednak przy uruchomieniu tej maszyny przez virt-managera dostaję komunikat:

Kod:

Error starting domain:...  xend.err "Error creating domain: Boot loader didn't return any data!"

Grub jest zainstalowany tak, że z poniższego wynika (chyba), że siedzi tak jak trzeba  w MBRarch.

Kod:

XenPV@#head -c512 /dev/xvda |tr -cs '[:print:]'  ' '
GRUB Geom Hard Disk Read Error

Czy można uruchamiać w ten sposób maszynę w trybie PARA wirtualizacji?

Dzięki Bercik, zrobiłem tak jak mówisz i jest połowiczny postęp.

Kod:

vcpus = 1
#bootloader = "/usr/bin/pygrub"
kernel = "/etc/xen/vmlinuz-2.6.32-5-amd64"
ramdisk = "/etc/xen/initrd.img-2.6.32-5-amd64"
on_poweroff = "destroy"
on_reboot = "destroy"
on_crash = "destroy"
vfb = [ "type=vnc,vncunused=1,keymap=pl" ]
vif = [ "mac=00:16:36:2c:6b:de,bridge=xenbr0,script=vif-bridge,vifname=vif7.0" ]
# próbowałem dla file i tap:aio  (xvda, sda, hda)
disk = [ "tap:aio:/var/lib/xen/images/Debian-6.0-amd-64-paravirt.img,sda,w" ]
#disk = [ "file:/var/lib/xen/images/Debian-6.0-amd-64-paravirt.img,sda,w" ]

System DomU ładuje się tylko do płowy, nie może zamontować systemu plików. Scieżka do img jest poprawna i to działw w pełnej wirtualizacji. Próbowałem w konfigu zmieniać file i tap:aio  (xvda, sda, hda) i nic.
Co z tym dyskiem, dlaczego xen nie może go podmontować?

Re: Xen PARAvirtualizacja - boot loader didn't return any data

1. jakie "prawdziwe dyski", co przez to rozumiesz i czy jestes tego peiwn (podmontowales/sprawidziles)?
2. czy ten .img to obraz dysku z partycjami czy pojedynczej partycji?
3. dobrze zeby jeszcze plik konfiguracyjny zen'a zawieral parametr root="" wskazujacy na urzadzenie ktore zawiera partycje glowna ... xen przekazuje to do jadra ...

Re: Xen PARAvirtualizacja - boot loader didn't return any data

1. Przepraszam, chyba się pomyliłem bo nie da się ich podmontować.. Natomiast jak zacznę czytać ten plik:  cat /dev/xvda1 to leci ekran za ekranem krzaczków; cat /dev/xvda2 wyświetla tylko kilkanaście znaków (bo to tylko extended), dla cat /dev/xvda5 znowu leci dużo znaków.
2. Plik img zawiera obraz całego dysku. Są tam trzypartycje: pierwsza LInux ext3, druga rozszerzona i trzecia swap.

Kod:

[root@localhost xen]# /sbin/fdisk /var/lib/xen/images/Debian-6.0-amd-64-paravirt.img 
last_lba(): I don't know how to handle files with mode 81ed
You must set cylinders.
You can do this from the extra functions menu.

Command (m for help): p
Disk /var/lib/xen/images/Debian-6.0-amd-64-paravirt.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

                                             Device Boot      Start         End      Blocks   Id  System
/var/lib/xen/images/Debian-6.0-amd-64-paravirt.img1   *           1        1461    11734016   83  Linux
Partition 1 has different physical/logical endings:
     phys=(1023, 254, 63) logical=(1460, 240, 60)
/var/lib/xen/images/Debian-6.0-amd-64-paravirt.img2            1462        1530      550913    5  Extended
Partition 2 has different physical/logical beginnings (non-Linux?):
     phys=(1023, 254, 63) logical=(1461, 18, 28)
Partition 2 has different physical/logical endings:
     phys=(1023, 254, 63) logical=(1529, 167, 46)
/var/lib/xen/images/Debian-6.0-amd-64-paravirt.img5            1462        1530      550912   82  Linux swap / Solaris

3. Do pliku konfiguracyjnego xena doałem root tak:

Kod:

kernel = "/etc/xen/vmlinuz-2.6.32-5-amd64 root=/dev/xvda1 ro"
extra = "root=/dev/xvda1 ro"
root = "/dev/xvda1 ro"

i nadal jest to samo - nie chce podmontować root FS.

Re: Xen PARAvirtualizacja - boot loader didn't return any data

a musisz bawic sie na plikach .img? ... osobiscie nigdy tak nie uzywalem xen'a ... bo jezeli nie to zrob to moze z normalnej pratycji lub lvm-a ...
