Re: [Xen-users] Problem with direct pass two (whole) raw disks to vm

[Jason Yu <yugn@xxxxxx>]

Many thanks Ian!!!

>>> If you only care about PV access to /dev/sd{a,b} (as opposed to emulated IDE) then you could also try putting them on xvde and xvdf (out of the say of the IDE stuff). That might help.

Could you please advise how to do this as I’m quite new to Xen? Do I simply do this in .cfg like this? 

disk = [ "file:/etc/xen/images/NAS-OMV.img,hda,w", "phy:/dev/sda,xvde,w", "phy:/dev/sdb,xvdf,w" ]

>>> Does the 1 (additional) disk case work regardless of whether you use sda or sdb?

Yes, I tried passing both sda and sdb individually. I could see each of them in domU (openmediavault web GUI). The start up time of the domU was swfit.

>>> Here you have hda, hdb and hdd.

I noticed this as well. (I think it was a typographical error.)So I edited the cfg again and created the vm (with two disks). Same problem. VM got stuck in a count down( see 1st email thread) and I couldn’t log into the web GUI. 

============ part of NAS-OMV.cfg ==============

disk = [ "file:/etc/xen/images/NAS-OMV.img,hda,w", "phy:/dev/sda,hdb,w", "phy:/dev/sdb,hdc,w" ]

Soon after creating the vm, I ran this:

Thanks Ian for the reply! Here is the output. Can you see any

Here you have hda, hdb and hdd.

But here it seems to create hda, hdb and hdc. I'm not sure what that is

all about, but it seems odd. Can you try giving hda/b/c in your config?

Other than that I'm not seeing anything strange about your logs. Can you

post the output of "xenstore-ls -fp" while the problematic domain is

running please.

If you only care about PV access to /dev/sd{a,b} (as opposed to emulated

IDE) then you could also try putting them on xvde and xvdf (out of the

say of the IDE stuff). That might help.

Does the 1 (additional) disk case work regardless of whether you use sda

or sdb?

Ian.
