A few days ago I reported a bug with respect to console problems after the
<bootloader /> bug was 'solved'. Now the status of it did not change, nor
did anyone comment.
Any updates?

Don't report new bugs in old bugzilla tickets. One bug report per ticket.
I posted a patch which related to Xen text console handling on monday
afternoon which may or may not be related - I can't tell with your rather
limited bug description of 'console problems'

New subject: [libvirt] Libvirtd needs to be always running/
Hi All,
A newbie question:
Does the libvirtd need to be running all the time if I want to use any
functions of libvirt (as simple as start/stop/pause my virtual machines
(qemu/zen)). Or is it only try if I use the remote functions or virsh.
Thanks,

Hi, Yao
You should differenciate Qemu and Xen(zen).
For QEMU, libvirtd need to run always.
For Xen, it does not requrired to run for local machine. and required to run for remote
machine.
Thanks

Some people still have their hopes that libvirtd will do the same for
Xen in the near future :)

Thanks Atsushi and Stefan,
It seems that libvirtd has to run with root, is this true?
But why does libvirtd need to run for QEMU? If it's for start/stop/pause vm,
is Qemu's command line tool not enough?
Thanks!

To make itself useful it should be root yes.

I presume it works by keeping reference to the domain, and is not able to
manipulate the domain if it does not own it... but this is a guess :)

Yes, because it has todo lots of privileged jobs, such as starting
QEMU with permissiong to use /dev/kvm, accessing disks and logical
volumes in /dev, creating TAP devices, creating bridge devices,
and much more. That said, if you were to chmod/chown all the devices
in question, you could run libvirtd unprivileged - it requires alot
of setup ahead of time though.
But why does libvirtd need to run for QEMU? If it's for

Libvirt does much more than just starting/stopping QEMU. It interacts
with its monitor console to control many aspects of it at runtime. It
also tracks state of running VMs to detect shutdown & cleanup, and
also manages storage, and networking state.

The answer is yes & no.
Libvirtd does *not* need to be running if you want to control the
local Xen hypervisor. In this case libvirt makes direct hypervisor
calls and/or uses a connection to xend to do its work.
It *is* needed for:
- remote access
- non-root access
- if you use the network or storage features
- managing QEMU and KVM instances
If libvirtd isn't running you will get a warning, but that can just be
ignored.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
