[Xen-users] Re: Xen nexentastor-3.0.2-xen.cfg (blktap)

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Apply two patches attached to current http://xenbits.xensource.com/xen-4.0-testing.hg
( r4 is good as well)
1. First patch per Mark Johnson
2. Second patch per exeCooler.
Currently i run NexentaStore Xen instance under Xen 4.0.1-rc4 ( 2.6.32.16) on top of F13, but Debian as a base shouldn't make much difference ( udev <= 151).
But , Nexenta is 64-bit.

Hi!

Sorry that I maybe disturb you,
I have the problem to get nexenta running with xen and read many things that you posted.
So I think you have the most experience with this.

I tried to apply the patches you talked about:

http://www.gossamer-threads.com/lists/xen/devel/178392
http://bderzhavets.wordpress.com/2010/07/11/execoolers-patch-for-xen-4-1-unstable/


Do you know of a working setup for getting xen + nexenta running under Debian?


I want to use nexenta (32bit because cadp)  + adaptec (passthrough) + HP LTO2 448 (ndmp in nexenta)
with xen because nexenta on it's own doesn't like my two SATA-Controllers,
even if it shows my disks when using iostat, I can't get the disks to work.

Thx in advance.






And tried to edit the nexenta-xen-cfg multiple times like:

disk =  [
        'tap2:tapdisk:vhd:' + work_dir + '/' + disk_1_name + ',xvda,w',
...
        ]

debian:/opt/vm/nexenta# xm create -c nexentastor-community-3.0.2-xen.cfg
Using config file "./nexentastor-community-3.0.2-xen.cfg".
Error: Boot loader didn't return any data!




or:

'tap:tapdisk:vhd:' + work_dir + '/' + disk_1_name + ',xvda,w',

debian:/opt/vm/nexenta# xm create -c nexentastor-community-3.0.2-xen.cfg
Using config file "./nexentastor-community-3.0.2-xen.cfg".
Error: Device /dev/xvdp (51952, tap) is already connected.



'tap:vhd:' + work_dir + '/' + disk_1_name + ',xvda,w',
