USB Redirection hack on Two Node Controller+Compute Neutron GRE+OVS Fedora 20 Cluster

Up

Down

I clearly understand that only incomplete Havana RDO setup allows me to activate spice USB redirection communicating with cloud instances. There is no dashboard ( Administrative Web Console ) on Cluster. All information regarding nova instances status, neutron subnets,routers,ports is supposed to be obtained via CLI as well as managing instances, subnets,routers,ports and rules is also supposed to be done via CLI, having carefully watch sourcing “keystonerc_user” file to manage in environment of particular user of particular tenant. read more...

Gluster 3.4.2 on Two Node Controller+Compute Neutron GRE+OVS Fedora 20 Cluster

Up
vote
Down

This post is an update for "Setting up Two Physical-Node OpenStack RDO Havana + Neutron GRE + Gluster backend for Cinder" on Fedora 20 boxes with both Controller and Compute nodes each one having one Ethernet adapter. It’s focused on Gluster 3.4.2 implementation including tuning /etc/sysconfig/iptables files on Controller and Compute Nodes.
Copying ssh-key from master node to compute, step by step verification of gluster volume replica 2 functionality and switching RDO Havana cinder services to work with gluster volume created to store instances bootable cinders volumes for performance improvement. Of course creating gluster bricks under “/” is not recommended . It should be a separate mount point for “xfs” filesystem to store gluster bricks on each node. read more...

This post is sample of utilizing optimized paravirtualized PVHVM drivers (also called PV-on-HVM drivers) with Xen fully virtualized HVM guests running Ubuntu 3.1 kernels at Xen 4.1.2 Dom0. Xen PVHVM drivers completely bypass the Qemu emulation and provide much faster disk- and network IO performance. First thing I had to do it was rebuild the recent Ubuntu kernel for precise Ubuntu-3.1.0-3 with CONFIG_XEN_PLATFORM_PCI=y. As result following debian packages gets created. read more...

Set up Ubuntu PV DomU via xen-image-create at Xen 3.3 Ubuntu Dom0 with Novell kernel 2.6.27

vote
Down

I would also name this post xen-image-create&debootstrap vs python-vm-builder in regards of pre-building Xen Guests at Ubuntu Intrepid Server.View Bug #311943 at https://bugs.launchpad.net/ubuntu for details. Install Intrepid Server Dom0 with with Novell’s Xen-ified kernel, enabling Dom0 and DomU support at a time.Tune xen-tools scripts per [1] and create Intrepid PV DomU. Actually, images been created via xen-create-image allow to upgrade DomU to real Intrepid Server PV DomU.
I mean to perform at originally loaded DomU :-

# apt-get upgrade
# apt-get install linux-image-server

and switch DomU’s kernel to vmlinuz-2.6.27-9-server.
Afterward images may be scp’ed to any Xen 3.3.X Linux Dom0(64-bit) and corresponding Intrepid Server PV DomU loaded for instance at Xen 3.3.1-RC4 CentOS 5.2 Dom0 (64-bit).So, xen-image-create appears to be responsible to prebuild Xen Guest instead of the most recent release of python-vm-builder.
