Timeout connecting to block device driver

Timeout connecting to block device driver

[Jacob Gorm Hansen]

hi,

with the latest tarball I am seeing the following error:

<6>xen_blk: Initialising virtual block device driver
<4>xen_blk: Timeout connecting to device!

I have tried all permutations of grant table and blktap drivers in
linux0 and linuxU, to no avail.

I am using vm-tools-0.1.9 and am fearing the problem could lie in there.
Has the interface for registering with blkdev backends changed recently?

thanks,
Jacob

We switched over to xenbus/xenstore on Friday. So blk devices don't use 
the control interface any more.

ok,
is there any documentation or code I can look at to figure out how to
give a domain access to a block device, using my own code or vm-tools?

There is not an officially released version of vm-tools that has been 
updated for the store (yet).  Once the store-work is complete, a new 
version will be released.
