[asterisk-users] Virtual machine timing (KVM)

[Bruce Komito]

FWIW, we recently moved a 1.4.29 Asterisk system onto a VMWare guest machine and with 40+ call legs (20+ calls), it isn't even breaking a sweat.  We have had no complaints from users nor have we noticed any degradation in voice quality, be it live, voicemail or conference bridge (with six participants).  The underlying hardware is an HP ProLiant DL360 G5 (Xeon 5160 3gz, 2 cores) with 20gb of memory and the VMWare version is ESXi 4.

The 2.2.1 version of DAHDI using DAHDI dummy seems to be working adequately in a Xen environment on CentOS for me, although I haven't been using MeetMe.  Have you run into issues with it specifically?  Which version of DAHDI are you using?  If there are some issues that you have found I would like to know...

Thanks,

Sean
