Good afternoon.
Interested in the answer to this question: is there a difference in installing asterisk (v11) on a regular iron server or on a virtual one (KVM).
OS Debian 6.
Asterisk will be used for sip and WebRTC tests.
Thanks

My clients on KVM virtual machines have asterix spinning, I'm not complaining. But dom0 is kept unloaded, la above 4 is rare.

It all depends on how busy the host system will be. If for tests - that all the same. If production - you can rest against the system timer and get the sound "like from a pipe"

For "tests" in my opinion there is not much difference ...

There is a difference under heavy load, because. real-time traffic in a virtual environment is a delicate matter.
I put all my production servers STRICTLY on pieces of iron.

there is a difference. time can "run away" in a virtual machine. the simplest test is to give the virtual machine 10% cpu and run any cpu-bench for us.

there are a lot of little things, but it should be easier on kvm than on openvz for me
