Arindam,

What happens if you 'apt-get remove python-guestfs' and try? I'd expect it to 
fallback to nbdmount.

Hi,
I have a working Openstack Grizzly setup with nova-network on Scientific Linux. 
As, SL comes with a old qemu:

qemu-kvm-0.12.1.2-2.355.el6_4.6.x86_64

I am trying to upgrade it to qemu-1.7.0 from source.

The configuration output.

As, openstack use /usr/libexec/qemu-kvm to start up VM, i linked
qemu-kvm to qemu-system-x86_64:

/usr/libexec/qemu-kvm -> /usr/local/bin/qemu-system-x86_64

But when I try to start VM, I get following error:

Reading your log, I don't think the problem is due to injection failure at 
libguestfs. It's a warning and is ignored.

Seems more like a network setup issue. Are you using neutron? Is the 
network/subnet etc setup properly?

Hi,
both
/sys/kernel/debug/tracing/tracing_on
/sys/kernel/debug/tracing/events/kvm/enable is 1.

The logs are:

libvirtd-debug<http://paste.openstack.org/raw/72197/> (sorry for lots of 
garbage in this file)

/var/log/messages<http://paste.openstack.org/raw/72198/>

instance.log<http://paste.openstack.org/raw/72205/>

After disabling tracing_on and tracing kvm events, it gave the same error.

If you can that'll be great. Thanks.

Also what's in

/sys/kernel/debug/tracing/tracing_on
/sys/kernel/debug/tracing/events/kvm/enable

Try running after
echo 0 > /sys/kernel/debug/tracing/tracing_on

If there's no improvement try - although I don't know what it really does (I 
need to read the code)
echo 0 > /sys/kernel/debug/tracing/events/kvm/enable

I'm just wondering if it's due to some permission/ACL issues when trying to 
write into debugfs using ftrace, given your observation on different tracing 
backends.

Thanks for reporting and spending time on this.

Cheers

Is it a single node deployment? Do you have any other log data such as 
libvirt_debug.log, libvirt/qemu/instance-.log? Any errors/warnings during 
the time of instance creation in syslog?

Arindam,

If you don’t want to see the error in the logs you can configure 
/etc/nova/nova.conf to

[libvirt]
inject_partition = -2

The guest can then inject files and metadata after it starts up, which is more 
preferable.

Bug I forget what is version of the guestfs. If you can't deal the problem, I

The guestfs error is due to a misconfiguration of guestfs and will only result 
in not having files injected before booting. Usually this is harmless as 
cloud-init like software will fix it after booting.

Glad the VM booted :)

You can upload your custom kernel/rootdisk pair to glance and use the rootdisk

Now i need to boot VM from the openstack dashboard(controller node) onto

Therefore my question is whether can we boot VM from controller node onto

Or rather, the compute cannot talk to the conductor. Try setting use_local=true
