Re: [Openstack] Suggestion for lab environment
@Adam Thanks. I was actually running Virtualbox on top of Linux host. Sorry I should have mentioned that. When I started reading various docs relating to Openstack found lot of people building lab env on it. Also, it was the quickest to start with as I already had few VMs running on it. But now I understand (thanks to you for the pointers relating to various components of VBox) the setup of VBos wasn't probably the best one. ESXi was/is definitely the better choice, I understand that. But that means I'll have blow my ,unfortunately, only machine and re-install the ESXi on it. Just didn't want to do that at the start. But I like Don's idea to use KVM instead. I'm just trying to learn openstack and really just looking for a 'useable' vm instances running on it (even if it runs under Vbox/KVM/esxi). @Don, Thanks. As mentioned above, I like the idea of running openstack on KVM. I'll head in that way. Will see how it goes. One question, do I still have to use libvirt_type=qemu on compute node running under KVM? regards Maruf On Sun, Oct 19, 2014 at 6:26 AM, Don Waterloo don.water...@gmail.com wrote: On 18 October 2014 09:25, Md.

You are on the right track with the libvirt_type= comment. Your issue is that qemu is emulating the instructions. I normally run OpenStack in a kvm virtual machine on my Linux system and get very good performance. I don't believe it is possible to get good performance under VirtuallBox tho (since it doesn't pass the vt-x). ___ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack

VirtualBox is not a bad choice when using lightweight guests on it, for example CirrOS (http://download.cirros-cloud.net/). But of course you do not want to use Windows or a full blown Linux on top of QEMU. Maybe you could try KVM with Nested Virtualization. https://wiki.archlinux.org/index.php/KVM#Nested_virtualization Christian. -- Christian Berendt Cloud Solution Architect Mail: bere...@b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg / http://www.b1-systems.de GF: Ralph Dehner / Unternehmenssitz: Vohburg / AG: Ingolstadt,HRB 3537 ___ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
Re: [Openstack] Suggestion for lab environment
Anytime you put install a portable dev environment running embedded guests on top of what amounts to commercial bloatware such as Windows, you'll have performance issues. Could also be as simple as how you built your VirtualBox (static disk = fast, dynamic disk = slow, less memory = more paging to disk = disk type matters). Technically speaking though assuming your budget is $0, VMware hypervisors are actually free ( http://www.vmware.com/products/vsphere-hypervisor) and useful when comparing performance. You need a dedicated machine for it but exploring options couldn't hurt.
