Hi,
I just compiled latest git to work on Bug #585113 .
Unfortunately, I can't start the the VMs with the device mappings
generated by our multipath
setup.

Argument list too long
Might be a problem with the colon in your file name (the error message
is nonsense - I'll send a patch). It takes everything before the first
colon as a protocol name. To work around this you can specify the
protocol explicitly, as in -drive file=host_device:/dev/mapper/...
applied your patch, the actual error is (e.g.):
qemu: could not open disk image
/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-e1861b105-4cb000e7e8c4bf3b-opensuse-11-2-i586:

while the image is there:
