Hi list,
Currently, monitoring QEMU virtual machines with standard Unix
sysadmin tools is harder than it has to be. The QEMU command line is
often miles long and mostly redundant, it's hard to tell which process
is which.
This patch reorders the QEMU -name argument to be the first, so it's
immediately visible in "ps x", htop and "atop -c" output.
Patch attached and also available from my github fork (master @
git://github.com/intgr/libvirt.git)
Regards,
Marti

These two paragraphs belong better as the commit message.

Subject: [PATCH] qemu: Move -name arg to be the 1st so it's visible in "ps
x"
output etc
This is a bit long; I trimmed it in length so that 'git shortlog -30'
doesn't wrap so badly:
qemu: move -name arg to be 1st in "ps x" output
- cmd = virCommandNewArgList(emulator, "-S", NULL);
+ cmd = virCommandNewArgList(emulator, NULL);
Once you get down to no args, it's more efficient to do:
virCommandNew(emulator);
And one BIIIIG problem - making this change means that 'make check'
fails, unless you update ALL of the tests to match. But I agree with
the concept, so I was okay making the change (sed scripting to the
rescue, thankfully).
ACK with those modifications, so I will push once I complete the
testsuite conversion. I will also be adding you to AUTHORS; let me know
if you prefer a different spelling than what you used to make your commit.

Oops, obviously I'm new to libvirt development. :)

Thanks, this ID is good.

Thankfully, we had very few named VMs in our testsuite - I only had to
touch 15 files.
