guestmount failing to mount a qcow image
by Pádraig Brady
I've been able to mount this image with qemu-nbd on Fedora 15 with:
mkdir pb.test
cd pb.test
wget http://www.pixelbeat.org/guestfs/annoying.qcow2.gz
wget http://www.pixelbeat.org/guestfs/77de68daecd823babbb58edb1c8e14d7106e83bb...
gzip -d *.gz
mkdir -p /var/lib/nova/instances/_base/
mv 77* /var/lib/nova/instances/_base/
modprobe nbd
qemu-nbd -c /dev/nbd1 annoying.qcow2
mkdir t
mount /dev/nbd1 t
ls t
umount t
qemu-nbd -d /dev/nbd1
However guestmount on RHEL6.2 and Fedora 15 does this:
# guestmount --rw -a /tmp/disk -i /tmp/tmplFlBCc
libguestfs: error: mount_options: mount_options_stub: /dev/root: No such file or directory
guestmount: some filesystems could not be mounted (ignored)
# echo $?
0
# ls -lrt /tmp
ls: cannot access /tmp/tmplFlBCc: Input/output error
d?????????? ? ? ? ? ? tmplFlBCc
I've attached the debug output from the above run on RHEL6.2
cheers,
Pádraig.

failure converting Linux ESX guest to KVM hypervisor
by John Kienle
Hi,
I am experiencing a failure running virt-v2v to convert a Linux guest
on an ESX host to a RedHat KVM hypervisor. The output with the failure
follows. Any help/guidance is appreciated.

This patch adds value_data_cell_offset to the hivex ABI, to report the
hive space used for long (>4 bytes) value data.

[hivex] [PATCH 2/8] generator: Add new return type to ABI: RLenValue
by Alex Nelson
RLenValue is similar to RLenType, though with one less argument. This
required adding additional conversion functions for several languages'
bindings.
