[libvirt] [PATCH] sanlock: Use VIR_ERR_RESOURCE_BUSY if sanlock_acquire fails
by Jiri Denemark
When acquiring resource via sanlock fails, we would report it as
VIR_ERR_INTERNAL_ERROR, which is not very friendly to applications using
libvirt. Moreover, the lockd driver would report the same failure as
VIR_ERR_RESOURCE_BUSY, which looks better.
Unfortunately, in sanlock driver we don't really know if acquiring the
resource failed because it was already locked or there was another
reason behind. But the end result is the same and I think using
VIR_ERR_RESOURCE_BUSY reason for all acquire failures is still better
than what we have now.

[libvirt] [PATCH] qemu: fix index error when clean up vport profile
by Huanle Han
1. 'last_good_net' indicates the index of last successfully configured
net. so def->nets[last_good_net] should also be clean up if error occurs.
2. if error occurs in 'virNetDevMacVLanVPortProfileRegisterCallback'
(second 'goto err_exit' in loop), we should also do
'virNetDevVPortProfileDisassociate' cleanup for the
'virNetDevVPortProfileAssociate'(first code block in loop). So we should
consider the net is successfully configured after first code block in
loop finishes.

[libvirt] [PATCH 0/5] Prohibit use of 'index' for variable
by John Ferlan
Given the recent Xen-devel build failure/issue - this series of patches
will remove our uses of '[unsigned] int index' and then generate a rule
for it
John Ferlan (5):
qemu: Adjust the prototype to match the function
util: Use 'idx' instead of 'index'
snapshot: Change 'index' to 'idx'
nwfilter: Change 'index' to 'idx'
cfg: Disallow usage of 'index' as variable name

Date: Mon, 6 Apr 2015 22:56:25 -0500
Qemu-system-ppc64 has introduced new variants of pseries machine type,
such as 'pseries', 'pseries-2.1'..'pseries-2.3'. Replace the hardcoded
values in the schema with a regex that captures this.

[libvirt] [PATCH] qemu: Use 'idx' instead of 'index' for variable name

I did try modify cfg.mk to add a syntax check similar to the ii,jj,kk
checks, but it tripped up over 'index' declarations inside structures.
I'd be happy to add one, but I need some help formatting it... Here's
what I had:
sc_prohibit_int_index:
@prohibit='\<(int|unsigned) ([^(=]* )*(index)\>(\s|,|;)' \
halt='use different name than 'index' for declaration' \
