[WISPA] OT: Linux Virtualization
I have worked with Linux quite a little mainly with CentOS as an email server etc. I was curious about trying to do some virtualization now. Leaning towards FOSS. Seems like OpenVZ is easiest to implement but also looking at KVM and XEM also. Seems that CentOS 6 will be focusing on KVM. What else is everyone doing here? WISPA Wants You!

Re: [WISPA] OT: Linux Virtualization
I would recommend XenServer from Citrix (it's the commercial offering of the open source project) but they offer a free version. It has a very easy to use GUI, and also has a command line interface. We virtualize all our servers as it allows us to do full OS backups fairly easy. Plus in the event of a hardware failure, you can move VM's to another server with different hardware easily.

Re: [WISPA] OT: Linux Virtualization
We have used a number of these, done a ton of benchmarking and here is a quick summary of my opinions. This could end up being a holy war, but hope not. Almost all testing was run using iSCSI storage and typically bonded Gig interfaces and identical hardware/tests performed. We used pretty much the entire Phoronix test suite for getting overall comparisons. Here are my observations: 1. Both Xen and VMWare offer the best and easiest to use interface. If price was not a factor I prefer Vsphere but Xen is more reasonably priced. The free version of VMWare's stuff seems to be going away in version 5 so that might be an issue if you are going to use the free versions. 2. Unless you need Live Migration or some of the other features of the paid versions the free perform identical. 3. We saw them Xen/VMWare about 65%-75% of the bare metal results using our benchmarks (* see disclaimer below). 4. KVM based virtualization was near 75%-80% of bare metal (* again disclaimer) 5. Containers (OpenVZ or Proxmox (does KVM/Containers and nice web interface)) hit nearly 98% of bare metal! So, if you are virtualizing a lot of Linux systems and can live with the caveats of containers they provide excellent performance. 6. If you are looking to sell virtual machines to customers you might want to look at Parallels bare metal servers with the web addition. This works very similar to OpenVZ (they are related) and provides KVM/Containers. We have tested version 5 a bunch as well and performance matches the FOSS stuff, with a very nice interface. In addition it allows for all sorts of accounting/limits on disk, CPU, network traffic,... if needed. * There are two factors we have seen contributing to this. First, using iSCSI in a virt machine you get the drivers for the Ethernet dropping perf a few percent. Also, since the bare metal machine had ALL of the RAM, while we typically gave virtual machines 4GB for testing they were able to do more file/block caching which bumped rates on some of those tests. Your workload that you are looking to virtualize will be a big factor in picking the proper tool. We have all three in production at this point, but will probably settle on one going forward, most likely Containers/KVM since we like the blend of performance and versatility this provides in addition to the FOSS portion. * Larry A.

Re: [WISPA] OT: Linux Virtualization
It does, if you purchase the license for it. In my experience, Citrix XenServer was pretty nice save for one issue: the client tools did not install on every distribution. They are binary only and don't compile. The Vmware tools at least compile on Linux, so you can still get them installed to a distribution that isn't an exact match to one in the list. -- Adam Kennedy Network Engineer Omnicity, Inc.

Re: [WISPA] OT: Linux Virtualization
Yeah, it does. its a paid feature however. The free version doesn't do it. But the free version will live migrate. I run a small asterisk server on it. When I live migrate the audio just stops for about 3 seconds, And then picks right back up. Its awesome.

Re: [WISPA] OT: Linux Virtualization
We have been working with ProxMox, and so far we have been very happy with it. (it open source, full install of base platform based on Debian (lenny) with a web based management interface, it allows you to have either OpenVZ containers or KVM's as needed. Very efficient, stable and easy to manage. oh, by the way, it does also have clustering support, as well as the ability to move a running Live Vm from one box to another, (there is a bit of down time ... e.g moving a OpenVZ container will have a 5-10 second down time).

I would not suggest using a Linux distro and would go with a bare metal (vsphere, xen's alternative) FOSS virt stuff has come a long way since I first started using it 5 years ago. There a couple FOSS projects that I recommend to try out. The first and most mature is called Proxmox VE (http://www.proxmox.com/products/proxmox-ve) it is a bare metal Linux distribution that can be installed on most any server supporting Intel or AMD virtualzation instructions (most do). Proxmox is a Debian based distro so anything you can do with Debian can be done with Proxmox. This has lead to some cool things in terms of HA and replication that the community has built. The Proxmox feature set is not to bad, it is no Vmware enterprise plus but does the job. It is in active development has a nice easy to use web interface and supports clustering. Future releases (like the upcoming 2.0 release) will include things like HA out of the box. The second project is called OpenNode (http://opennode.activesys.org/) is similar to Proxmox in a few ways. OpenNode like Proxmox can do both OpenVZ and KVM. It is a CentOS based hypervisor and can be clustered. It is younger that Proxmox and the out of the box feature set is less. I however like how easy it is to customize and script various common tasks. It follows the standard way of doing things in Linux better than Proxmox does (IMHO) and is also lighter weight, I install the OS on flash based disks so space is a premium for me. It also will allow you to take a generic CentOS install and convert it to a OpenNode member easily. Both can use iSCSI or other type of shared storage for VM's, I have had great success with using iSCSI with both distributions, NFS not as much but that was do to some implementation stuff. As with anything I recommend you test stuff out and see what fits your environment best. That being said either of those projects will get you up and running fast with a minimal learning curve. I can answer more questions if you have them. Thanks, _ /-\ ndrew WISPA Wants You!

Re: [WISPA] Rocket M5 Dish high latency
The reason I ask is because we are using WDS on some M2 PtMP installations to relay connections to neighbors that are near other customers. A tech from UBNT told us that WDS is not designed to work with Airmax and it may be causing some issues with throughput especially upload. Has anyone else found this to be the case? We are needing to be able to consistently carry 50mbps or so off of these M5 bridges, is that doable or are we asking too much of this equipment?

I am going to throw my 2 cents in. On Mon, Jul 25, 2011 at 10:04 AM, Nick W lists-wi...@atomsplash.com wrote: I've been experimenting with both the last 2 weeks.

I would not suggest using a Linux distro and would go with a bare metal (vsphere, xen's alternative) FOSS virt stuff has come a long way since I first started using it 5 years ago. There a couple FOSS projects that I recommend to try out. The first and most mature is called Proxmox VE (http://www.proxmox.com/products/proxmox-ve) it is a bare metal Linux distribution that can be installed on most any server supporting Intel or AMD virtualzation instructions (most do). Proxmox is a Debian based distro so anything you can do with Debian can be done with Proxmox. This has lead to some cool things in terms of HA and replication that the community has built. The Proxmox feature set is not to bad, it is no Vmware enterprise plus but does the job. It is in active development has a nice easy to use web interface and supports clustering. Future releases (like the upcoming 2.0 release) will include things like HA out of the box. The second project is called OpenNode (http://opennode.activesys.org/) is similar to Proxmox in a few ways. OpenNode like Proxmox can do both OpenVZ and KVM. It is a CentOS based hypervisor and can be clustered. It is younger that Proxmox and the out of the box feature set is less. I however like how easy it is to customize and script various common tasks. It follows the standard way of doing things in Linux better than Proxmox does (IMHO) and is also lighter weight, I install the OS on flash based disks so space is a premium for me. It also will allow you to take a generic CentOS install and convert it to a OpenNode member easily. Both can use iSCSI or other type of shared storage for VM's, I have had great success with using iSCSI with both distributions, NFS not as much but that was do to some implementation stuff. As with anything I recommend you test stuff out and see what fits your environment best. That being said either of those projects will get you up and running fast with a minimal learning curve. I can answer more questions if you have them. Good info, thanks. If I go with Proxmox can I later switch to Opennode by simply copying my virtual machines over to Opennode? Is OpenVZ preferred over KVM for linux applications that do not care about the shared kernel? Initially I am just thinking a dual or quad core socket 1156 processor with say 8 to 16G of RAM and a few terrabytes of disk in software RAID1.

You may have to ssh into the radio's and issue the following commands to make sure that ethernet interfaces are not dropping any packets. ... ifconfigto show status or ethtool eth0 to show handshake...

Yes, you can easily switch between the two distros, the back end tech (KVM and OpenVZ) is the same for them both. So moving can be a simple rysnc and some minor tweaks. Proxmox will not support software RAID, the community as a whole seems to frown upon it. That does not mean that it will not work but it will take some manual tweaking. OpenNode does not really care what hardware you use and so are forgiving to things like software raid, at least more so than Proxmox. If you make a clustered environment, which is possible with either distro you can migrate the box to another host without any downtime. The host that you move it to can be bigger faster hardware. You can also make a backup of the machine and restore it to newer hardware if a little bit of down time is acceptable. I hope this helps, _ /-\ ndrew WISPA Wants You!

I would not suggest using a Linux distro and would go with a bare metal (vsphere, xen's alternative) FOSS virt stuff has come a long way since I first started using it 5 years ago. There a couple FOSS projects that I recommend to try out. The first and most mature is called Proxmox VE (http://www.proxmox.com/products/proxmox-ve) it is a bare metal Linux distribution that can be installed on most any server supporting Intel or AMD virtualzation instructions (most do). Proxmox is a Debian based distro so anything you can do with Debian can be done with Proxmox. This has lead to some cool things in terms of HA and replication that the community has built. The Proxmox feature set is not to bad, it is no Vmware enterprise plus but does the job. It is in active development has a nice easy to use web interface and supports clustering. Future releases (like the upcoming 2.0 release) will include things like HA out of the box. The second project is called OpenNode (http://opennode.activesys.org/) is similar to Proxmox in a few ways. OpenNode like Proxmox can do both OpenVZ and KVM. It is a CentOS based hypervisor and can be clustered. It is younger that Proxmox and the out of the box feature set is less. I however like how easy it is to customize and script various common tasks. It follows the standard way of doing things in Linux better than Proxmox does (IMHO) and is also lighter weight, I install the OS on flash based disks so space is a premium for me. It also will allow you to take a generic CentOS install and convert it to a OpenNode member easily. Both can use iSCSI or other type of shared storage for VM's, I have had great success with using iSCSI with both distributions, NFS not as much but that was do to some implementation stuff. As with anything I recommend you test stuff out and see what fits your environment best. That being said either of those projects will get you up and running fast with a minimal learning curve. I can answer more questions if you have them. Good info, thanks. If I go with Proxmox can I later switch to Opennode by simply copying my virtual machines over to Opennode? Is OpenVZ preferred over KVM for linux applications that do not care about the shared kernel? Initially I am just thinking a dual or quad core socket 1156 processor with say 8 to 16G of RAM and a few terrabytes of disk in software RAID1. I am assuming the nice thing about containers is I can easily move everything down the road to better/faster hardware? WISPA Wants You!

[WISPA] just installed a Huawei...
Not sure if it's any interest of this group, but I just installed a Huawei CX600 router this last week. It's like Cisco quality (garbage!) for the price that Cisco should be (low!). The commands are very similar (e.g. switchport - portswitch, no shut - undo shut, etc), and you configure it almost identical to what you'd expect on a Cisco. The worst part about the Huawei is probably the documentation. It's scattered all over the place, so if you want something simple (like telnet access), it's in a completely different PDF than if you want, say, VLAN configuration commands. Finding it all is a huge scavenger hunt. But hey...for like a 1/4 of the price or whatever (so I've heard), I'd say it's worth it. :b -- Also on LinkedIn?
