Re: [OpenStack] Xen Hypervisor
Hi Alexandre,
I am just bumping into this thread, so forgive me if I'm stating the obvious.
--flat_network_bridge=br100
I think there's a good chance this is not the correct bridge.
This will cause 'br100' to go into the 'bridge' column into the 'networks' table. However, XenServer does not have such network.
I also see:
--network_manager=nova.network.manager.FlatDHCPManager
This means nova will just try to plug VIFs into 'br100', as the FlatDHCPManager does not create bridges (unlike the VLAN manager).
I would suggest to use nova manage to destroy this network which uses br100 as a bridge, update the flag to xenbr0 and then create a new network (nova-manage reads that flag);
Finally,
--flat_interface=eth0
My memory might be failing me here, but I think this is the interface on the network node where dnsmasq listens for DHCP messages. In the libvirt world, this turns out to be also the interface on top of which the flat_network_bridge is built; in the xenapi world, this is the interface in nova's domU where dnsmasq should be listening, and it should match the VIF plugged into flat_network_bridge.
I hope you'll find these information useful.
Regards,
Salvatore
PS: One more thing: I also see a 'CannotSendRequest' exception being raised. That sounds like the connection between dom0 and domU was temporarily lost. Do you have more information it?

Well,
In this moment, i have just one NIC on my dom0 and i can't create VLANs because of the current infrastructure. There is anyway to test this? I'm not using DevStack as i said in old replies.
Thank you all for your help.

Hi,
Here is my nova.conf from Xen Nova-compute: http://pastebin.com/YSANE0pN
I have just one NIC on dom0, that's a problem?
My infrastructure is (All IPs start with 192.168.100):
gateway: .1
dhcp: .4
controller: .139
dom0: 251 (Xen)
domU: 214 (Xen PV)
Also, here is my ifconfig of Dom0:

Subject: RE: [Openstack] [OpenStack] Xen Hypervisor
Hi,
That looks a lot like you have some of the networking flags not quite correct for your setup.
I have attempted to describe the flags on the wiki, which might help you:
http://wiki.openstack.org/XenServer/NetworkingFlags
I am not 100% sure, but it looks like the following flag has the wrong value:
flat_network_bridge
On XenServer it should reference the bridge (or bridge name) on your XenServer that you want instance traffic to go through. It could by eth1 (if you want the traffic on your second nic to hold guest traffic) or on xapi1 (if you have setup a VLAN network bridge to carry the instance traffic).
If you can tell us:
* What this returns: xe network-list
* What you want to use each of the above networks for
* And what is in your nova.conf
I might be able to be more specific.
Hope that helps,
John

Hi,
I have edited the xenhost plugin to use "host_uuid=_run_command("xe host-list --minimal").strip()" instead of original command. Now, i'm with this logs on nova-compute... Also i dont know how to trace xenapi_conn.call_plugin to find out why my host_uuid isn't getting set, can you help me?

Yes, I'd missed the code change in xenapi_conn. Alexandre, are you sure you have a matched pair of nova-compute and the nova plugins? If so, then please trace through xenapi_conn.call_plugin to find out why your host_uuid isn't getting set. It looks like it should to me, even on XCP.
Thanks,
Ewan.

Subject: RE: [Openstack] [OpenStack] Xen Hypervisor
I certainly changed the plugin so it always required the host_uuid, but I also changed the "call_plugin" code in xenapi_conn to ensure we always pass the host_uuid.
Indeed it looks like in the code path below, that you should get the host_uuid passed all the way though.
I have not tested with XCP myself, only with XenServer 6. I am afraid I will not get chance to try this out till Wednesday (currently on holiday). One other useful log will be from XCP where it logs the parameters passed into the plugin (on XenSever it is /var/log/xensource.log, it could be /var/log/xcp.log? or xapi.log, can't remember I am afraid) You should be able to track the host_uuid to ensure it gets from nova->xapi client->xapi server->plugin
If you want to move on with your deployment a work around is to add this into the xenhost plugin:
Change:
host_uuid=arg_dict['host_uuid']
Into:
host_uuid=_run_command("xe host-list | grep uuid").split(":")[-1].strip()
The above does not work in all cases, but it should work for your particular case (no pools).
If you could raise a nova bug for this, mentioning the version of XCP you are using, that would be great.
I hope that helps,
John

It looks like you're hitting a recently introduced bug (maybe). I haven't run the code, but from reading through, it looks like the xenhost.host_data plugin command is going to barf if it is not passed a host_uuid parameter. It used to gracefully handle that case, but since 37a392dc it's not doing so any more. The plugin is being called with no arguments from nova.virt.xenapi.host.
Cc'd John Garbutt, who wrote that bit of code.

Hi folks,
Sorry for late reply, i was trying to install this without following any ready-to-use scripts ( but i used one :( ) to understand how things are made. So i installed XCP 1.4.90 from DVD and configured it from installation screen.
Execute the following commands on dom0
------- Dom 0 Extra Config --------
cd /etc/xapi.d/plugins/
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/xenhost
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/xenstore.py
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/pluginlib_nova.py
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/migration
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/glance
wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/agent
chmod 777 *
service xapi restart
-----------------------------------
After that i downloaded XenCenter and created a VM from Ubuntu Server 11.10 CD... (all from below is on guest)
After this, i did updated all the system with command apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y and rebooted the machine. When you do this, you'll boot on newer kernel (3.0.0-16-server, check with uname -a command)... and unsinstall the old kernel (apt-get purge linux-image-3.0.0-12-server).
After this, i did installed the virtual kernel (3.0.0-16-virtual) and rebooted the machine. Check if you rebooted in this kernel via uname -a and unsinstall the old kernel.
After this, execute on dom0 again:
------- Dom 0 Extra Config --------
cd ~
wget http://94.212.78.134/res/xenserver/makepv.sh
chmod +x makepv.sh
./makepv.sh YOUR-XEN-GUEST-NAME
-----------------------------------
After this, you can do
apt-get install -y cracklib-runtime curl wget ssh openssh-server tcpdump ethtool python-pip git vim-nox sudo
and
pip install xenapi
wget http://images.ansolabs.com/xen/xe-guest-utilities_5.6.100-651_amd64.deb -O xe-guest-utilities_5.6.100-651_amd64.deb
dpkg -i xe-guest-utilities_5.6.100-651_amd64.deb
update-rc.d -f xe-linux-distribution remove
update-rc.d xe-linux-distribution defaults
mkdir -p /usr/share/cracklib
echo a | cracklib-packer
pwconv
echo root:password | chpasswd
rm -f /etc/localtime
groupadd libvirtd
useradd stack -s /bin/bash -d /opt/stack -G libvirtd
echo stack:password | chpasswd
echo "stack ALL=(ALL) NOPASSWD: ALL" >> etc/sudoers
mkdir -p /opt/stack
chown -R stack /opt/stack
After all this, you can install nova-compute , copy nova.conf from your controller and configure the following vars:
--connection_type=xenapi
--xenapi_connection_username=root
--xenapi_connection_password=password
--xenapi_connection_url=http://<<XENDOM0IP>>
and restart your nova-compute service.
You can test your XenAPI configuration using sudo nova-manage shell python and after pasting this
import XenAPI
import nova.virt.xenapi_conn
nova.virt.xenapi_conn.XenAPI = XenAPI
x = nova.virt.xenapi_conn.XenAPIConnection("http://<<XENDOM0IP>><http://%3c%3cXENDOM0IP%3e%3e>","root","password")
x.list_instances()
------
After all this things, i got Xen working, but i have a error with bridge now, as trace below:
2012-03-23 16:30:00,116 DEBUG nova.virt.xenapi [-] Updating host stats from (pid=23556) update_status /usr/lib/python2.7/dist-packages/nova/virt/xenapi_conn.py:488
