[asterisk-users] State of Asterisk+Virtualization+Timing

[Michelle Dupuis]

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.

Here is a link to the nice little blog entry I used a reference when doing this in testing... http://www.whmcr.com/2011/06/18/dahdi-in-lxc/
(Not my blog).
