Re: [asterisk-users] State of Asterisk+Virtualization+Timing
VMware is moving all server products to their ESXi engine. (The old VMware
"server" and ESX products are moving to legacy status - with these you could
actually do stuff on the kernel). ESXi is no longer a kernel you can mess
with, can't install drivers, etc. ESXi is being treated as an appliance that
you cannot and should not touch (even authorized partners like HP only get to
add software through VMware).
Many of these devices are not (and will not be) recognized by the VMware
kernel, so forgot about host support. At best you can pass-through the device
to a single guest, but then you lose the whole point of a shared timing source.

LXC (as is OpenVZ and Linux-VServer on Linux, BSD Jail and Solaris Zones) run on top of the host kernel. If you're allowed to create an arbitrary device, you can map yourself the disk and network and escape the jail. Thus those technologies also limit your ability to access devices and also typically outright deny the ability to mknod(2). With VMWare you'd probably be able to create device files, load DAHDI and whatever. You're running on a separate kernel instance. This gives better isolation, at the potential cost of performance. -- Tzafrir Cohen icq#16849755 jabber:tzafrir.co...@xorcom.com +972-50-7952406 mailto:tzafrir.co...@xorcom.com http://www.xorcom.com iax:gu...@local.xorcom.com/tzafrir -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Be sure to also create /dev/dahdi/{ctl,timer,pseudo,channel} for the

I've been using LXC in production for virtual asterisk hosts for well over a year now. I'd not mix an LXC container on the same host as a general purpose LAMP container, but as long as all the containers are well behaved then you shouldn't have any issues. At least I don't.

I have used both asterisk (1.4, 1.6.x and now 1.8) to separate machines where people should do their sip-registration (internet / intranet / pstn-gateway) and the actual dial-beast. Main advantage for virtualization is (besides easy scaling) that you can perform an upgrade in no-time (one VM-machine down, other up) Don't like it: back in seconds!

Re: [asterisk-users] State of Asterisk+Virtualization+Timing
Look at upgrading to at least 1.6.2 or 1.8, these both have newer timing sources that don't rely on dahdi. Also, if conferencing is a big deal, look at 10, this contains a complete rewrite of ConfBridge which doesn't require dahdi for mixing at all.

Take a look at: http://wiki.openvz.org/Asterisk_from_source You will have to compile dahdi and install it on the HN, and then you compile and install asterisk in the containers. I've not done this with chan_iax, but with meetme. In the case with meetme you would have to move some files over to trick asterisk that dahdi is compiled on the machine. The wiki mentions copying user.h. I used this as a starting point, some years ago: http://www.telephreak.org/papers/vpa/ This paper covers vserver, so it's not exactly the same - but the steps with tonezone was the same when I built the current server running this configuration. I'm in the process of building another server with openvz, so I'll need to refresh my memory and try to document the procedure. -- Med vänlig hälsning Johan Wilfer email: jo...@jttech.se JT Tech | Utvecklare webb: http://jttech.se direkt: +46 31 380 91 01 support: +46 31 380 91 00 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] State of Asterisk+Virtualization+Timing
Have you thought about using LXC rather than OpenVZ. There are a few references to allowing guest access to timing hardware online. I've only been playing with it recently and haven't used it in production yet but plan to soon. As for general thoughts about virtualising asterisk, I tried it in the past (about a year ago) on KVM and VMWare and it didn't work too well for me. Regardless of whether you are using LXC / OpenVZ / KVM / Whatever, you should be careful not to have too much other stuff running on the box. If asterisk has to wait to get CPU time you will really notice it, this isn't a problem with other applications like say a webserver.

KVM - Higher overhead, easier installation, 'true virtualization'. Primary issue is not timing per se, but KVM scheduling. Timing source, while present from dahdi_dummy natively may still not get proper scheduling by KVM process. This could also affect general call quality (even non IAX2 trunked voice), DTMF, etc. I have to believe there are others running virtualized Asterisk installations with some degree of success on OpenVZ or KVM.

[asterisk-users] State of Asterisk+Virtualization+Timing
Greetings- I'm about to dive into the process of virtualizing some of my Asterisk (primarily 1.4.x) infrastructure. In the past, when looking at virt solutions, the primary issue preventing me from moving was the lack of proper timing. We do not need it for MeetMe but rather for IAX2 trunking. I'd like to use either OpenVZ or KVM, but each seem to have independent "issues" that need to be addressed: OpenVZ - Better resource usage, lower overhead. Primary issue is how to grant access to host node timing source (physical device, or dahdi_dummy in /dev/dahdi/) to the containerized Asterisk process. KVM - Higher overhead, easier installation, 'true virtualization'. Primary issue is not timing per se, but KVM scheduling. Timing source, while present from dahdi_dummy natively may still not get proper scheduling by KVM process. This could also affect general call quality (even non IAX2 trunked voice), DTMF, etc. I have to believe there are others running virtualized Asterisk installations with some degree of success on OpenVZ or KVM.
