[Xen-users] XEN - Using morer than 4 block-devices in a single dom-u

["Guido Hecken" <guido.hecken@xxxxxxxxxxxxx>]

Hi list,

 

what's the magic to use more than 4 block-devices in a single Dom-U.

I tried to use a total number of 6 block devices (xvda to xvdf).

 

Anyone with more success on this?

 

Here are some informations and logs:

 

Disk Config:

 

disk = [ 'phy:/dev/virt_vm_vg/w2k_sbs,xvda,w', 'phy:/dev/daten_vg/fll_daten_vl,xvdb,w', 'phy:/dev/virt_vm_vg/db_home,xvdc,w', 'phy:/dev/daten_vg/fll_archiv_vl,xvdd,w', 'phy:/dev/daten_vg/fll_software_vl,xvde,w', 'phy:/dev/daten_vg/fll_archiv2_vl,xvdf,w' ]

 

 

/var/log/xen/qemu-dm-my-vm.log

 

Using xvda for guest's hda
Using xvdb for guest's hdb
Using xvdc for guest's hdc
Using xvdd for guest's hdd
Using xvde for guest's hde
qemu: drive `xvde' out of range
Using xvdf for guest's hdf
