Re: [openstack-dev] [nova] libvirt boot parameters
Hi,
I think that this variable is useful for me
cfg.IntOpt("reboot_timeout",
default=0,
help="Automatically hard reboot an instance if it has been "
"stuck in a rebooting state longer than N seconds. "
"Set to 0 to disable."),
cfg.IntOpt("instance_build_timeout",
but it seems that Eli is right: lbvirt driver doesn't implement this
function
def poll_rebooting_instances(self, timeout, instances):
pass
BTW I'm developing a feature: booting from network.
In my scenario sometimes the the booting instance pauses because the
boot source ( PXE) cannot answer on time.
Look at
6.4. Installing guest virtual machines with PXE
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6-Beta/html-single/Virtualization_Host_Configuration_and_Guest_Installation_Guide/index.html
I'll investigate on reboot_timeout and I'll inform you but thanks for
the tips
BR
Angelo

Subject: [openstack-dev] [nova] libvirt boot parameters
Hi all,
I need to add the option rebootTimeout when the instance boots.
If you use the *qemu-kvm*, boot parameter */reboot-timeout/* allows a
virtual machine to retry booting if no bootable device is found:
*/
# qemu-kvm --boot reboot-timeout=1000/*
Ref:
_https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6-Beta/html-single/Virtualization_Host_Configuration_and_Guest_Installation_Guide/index.html_
In Openstack a new boot parameter should be entered into Libvirt XML
attributes where required:
under the in the libvirt.xml file.
My idea is to add an option to nova boot command changing (nova API,
nova base,python-novaclient) but I would like to know what you think
about that?
Thank you beforehand
Angelo

As a general rule we aim to avoid exposing such low level config parameters via the APIs, since it is not in keeping with the cloud virtualization model which is to avoid exposing hardware configuration details to the users. It could be considered as a flavor extra specs parameter or image metadata property, depending on the use cases for us Regards, Daniel -- |: http://berrange.com -o-http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
