Comment 6 Yufang Zhang 2011-04-08 05:29:24 EDT
QA verified this bug with 2.6.32-128.el6:

1. create a RHEL6.1 HVM guest.

2. load the xenfs module.

3. # mount /proc/xen /mnt -t xenfs

4. # mount | grep -i xenfs
/proc/xen on /mnt type xenfs (rw)

5. # ls /mnt/
capabilities  xenbus

So change this bug to VERIFIED.

Comment 8 Yufang Zhang 2011-06-27 02:42:54 EDT
Hi Paolo,

Could I ask if there is any work porting xenfs into xen Windows Pv Drvier? (I mean use xenfs to transfer information between domainUs or between domainU and domain0. )

Comment 9 Paolo Bonzini 2011-06-27 07:30:53 EDT
If you mean Xenstore, it is indeed possible to implement IOCTLs on C: that do Xenstore operations.  However, it is not planned.
