Hi folks,<br><br>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.<br><br>Execute the following commands on dom0<br>------- Dom 0 Extra Config --------<br>cd /etc/xapi.d/plugins/<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/xenhost<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/xenstore.py<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/pluginlib_nova.py<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/migration<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/glance<br>wget -q https://raw.github.com/openstack/nova/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/agent<br>chmod 777 *<br>service xapi restart<br>-----------------------------------<br><br>After that i downloaded XenCenter and created a VM from Ubuntu Server 11.10 CD... (all from below is on guest)<br><br>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).<br><br>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.<br><br>After this, execute on dom0 again:<br>------- Dom 0 Extra Config --------<br>cd ~<br>wget http://94.212.78.134/res/xenserver/makepv.sh<br>chmod +x makepv.sh<br>./makepv.sh YOUR-XEN-GUEST-NAME<br>-----------------------------------<br><br>After this, you can do<br>apt-get install -y cracklib-runtime curl wget ssh openssh-server tcpdump ethtool python-pip git vim-nox sudo<br>and<br>pip install xenapi<br>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<br>dpkg -i xe-guest-utilities_5.6.100-651_amd64.deb<br>update-rc.d -f xe-linux-distribution remove<br>update-rc.d xe-linux-distribution defaults<br><br>mkdir -p /usr/share/cracklib<br>echo a | cracklib-packer<br>pwconv<br><br>echo root:password | chpasswd<br><br>rm -f /etc/localtime<br>groupadd libvirtd<br>useradd stack -s /bin/bash -d /opt/stack -G libvirtd<br>echo stack:password | chpasswd<br>echo "stack ALL=(ALL) NOPASSWD: ALL" >> etc/sudoers<br>mkdir -p /opt/stack<br>chown -R stack /opt/stack<br><br>After all this, you can install nova-compute , copy nova.conf from your controller and configure the following vars:<br>--connection_type=xenapi<br>--xenapi_connection_username=root<br>--xenapi_connection_password=password<br>--xenapi_connection_url=http://<<XENDOM0IP>><br><br>and restart your nova-compute service.<br><br>You can test your XenAPI configuration using sudo nova-manage shell python and after pasting this<br>import XenAPI<br>import nova.virt.xenapi_conn<br>nova.virt.xenapi_conn.XenAPI = XenAPI<br>x = nova.virt.xenapi_conn.XenAPIConnection("http://<<XENDOM0IP>>","root","password")<br>x.list_instances()<br><br>------<br><br>After all this things, i got Xen working, but i have a error with bridge now, as trace below:<br><br>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<br>2012-03-23 16:30:00,988 WARNING nova.virt.xenapi [-] Task [Async.host.call_plugin] OpaqueRef:d7a9f0df-0c7c-a760-6b76-3e985c747b1d status: failure ['XENAPI_PLUGIN_FAILURE', 'host_data', 'KeyError', "'host_uuid'"]<br>2012-03-23 16:30:00,992 WARNING nova.compute.manager [-] Error during report_driver_status(): ['XENAPI_PLUGIN_FAILURE', 'host_data', 'KeyError', "'host_uuid'"]<br>2<br><br>And yes, my permissions are 777 to all plugins.<br><br><div><div id="SkyDrivePlaceholder"></div>> From: todd.deshane@xen.org<br>> Date: Wed, 21 Mar 2012 11:04:19 -0400<br>> To: openstack@lists.launchpad.net<br>> Subject: Re: [Openstack] [OpenStack] Xen Hypervisor<br>> <br>> Just realized my reply was accidentally not sent to the list.<br>> <br>> On Tue, Mar 20, 2012 at 2:03 PM, Todd Deshane <todd.deshane@xen.org> wrote:<br>> > Please post specific error messages.<br>> ><br>> > Some general suggestions inline.<br>> ><br>> > On Tue, Mar 20, 2012 at 12:56 PM, Alexandre Leites <alex_tkd@live.com> wrote:<br>> >> Hi folks,<br>> >><br>> >> First let me say that i'm trying to install xen hypervisor and integrate it<br>> >> with OpenStack for more than one week.
