Cirros does not yet support DHCPv6, see
https://bugs.launchpad.net/cirros/+bug/1487041.

It also looks like other images will only do slaac by default, so you
would have to explicitly setup an DHCPv6 client in your guest, e.g.
for ubuntu-xenial do "sudo dhclient -6 ens3".

Subject: [Openstack-operators] [scientific-wg] high-performance/parallel 
file-systems panel at Barcelona

Hi all,

Just pondering summit talk submissions and wondering if anyone else
out there is interested in participating in a HPFS panel session...?

Assuming we have at least one person already who can cover direct
mounting of Lustre into OpenStack guests then it'd be nice to find
folks who have experience integrating with other filesystems and/or
approaches, e.g., GPFS, Manila, Object Storage translation gateways.

Hello,

If You are using virsh, You can apply such limits manually for each
instance. Check blkiotune command in virsh.

[Openstack-operators] IPV6 help liberty

[suresh kumar]

Hi All,

I have created IPv6 vlan in neutron with DHCPv6 stateful option, when I
create instances with this ipv6 vlan dhcp is failing to assign the IP to
instances and it is assigning link local address

I am able to ping the GW with link local address but not the
other instances on same vlan

Is there any configuration need to be done in neutron to make this work? my
ipv6 vlan is rotatable so I didn't attached to any router interface inside
neutron.

I don’t think we’ve figured out how to do this, but I’d certainly like to 
attend.  We have promised integration with Wrangler’s 10PB of lustre that sits 
across the hot aisle from us, so I probably need to figure out how to do this 
between now and Barcelona.

[Openstack-operators] Updating flavor quotas (e.g. disk_iops) on existing instances.

[Van Leeuwen, Robert]

Hi,

Is there an easy way to update the quotas for flavors and apply it to existing 
instances?
It looks like these settings are tracked in the “instance_extra” table and not 
re-read from the flavor when (hard) re-booting the instances.

Since the instance_extra flavor table is a big JSON blob it is a pain to apply 
changes there.
Anybody found an easy way to do this?

Thx,
Robert van Leeuwen
