Hi,
This is v9 of the patchset to support GlusterFS backend from QEMU.
Changes in v9
-
- Drop all inet_parse related patches from the patchset.
- Include generic URI parsing code from libxml2 and libvirt in QEMU and
use that in gluster block backend instead of private URI parsing

That's because I didn't do that explicitly, was always trying to

Hi,
While trying out -numa and -smp command line options, I found that it
is possible to specify inconsistent or impossible or incomplete
topology specifications on qemu command line and have qemu silently
boot a VM with such a topology without complaining.
Example 1: With "-numa node,nodeid=0,c
ing cpuid_apic_id before cpuid information is passed to
the host kernel.

Hi,
This set of patches enables QEMU to boot VM images from gluster volumes.
This is achieved by adding gluster as a new block backend driver in QEMU.
Its already possible to boot from VM images on gluster volumes using Fuse
mount, but this patchset provides the ability to boot VM images from glus
block: gluster as block backend
From: Bharata B Rao
This patch adds gluster as the new block backend in QEMU. This gives QEMU
the ability to boot VM images from gluster volumes.

This patch does two things:
- Adds GlusterFS specific init routines that enable QEMU to load

- Implements routines like gluster_open(), gluster_read(), gluster_write

- Fix a memory leak in qemu_gluster_create().
- Proceed with glfs_zerofill() only if glfs_ftruncate() succeeds in
