If you get root in a virtual server which has been assigned a PCI card, it is highly likely that you can use that PCI card to DMA to the host, gaining you root access in the host or any other virtual server. This problem can only be solved in hardware. Both Intel and AMD are working on it, some non-x86 vendors have had it for a while. /Benny ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I've understood that VMWare virtual machines cannot access physical hardware in the host machine directly, only the emulated hardware VMWare provides. As such, no T1/E1/POTS interfaces that connect via PCI. I'm not sure about the suitability of this route, but I would assume that any T1/E1/POTS USB devices out there would work, if they exist, because VMWare *does* allow the host's USB devices to connect to the guest.. Wasn't there talk on the list lately about a USB DS3 adapter? ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Asterisk under VMWare
Quoting WipeOut [EMAIL PROTECTED]: Anyone had any experience with an Asterisk server as a VMWare virtual machine? I was trying to run it under XEN and got into trouble so in all my searches, the conclusion was that running it under VMWare didn't work because of the faulty timer in VMWare... My problem with XEN was due to the fact that I needed access to a PRI card which I never managed to do (didn't try hard enough?). But my Asterisk at home works just perfect under XEN. I don't need hardware access there... XEN solves the timing issue different from VMWare so... ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Asterisk under VMWare; Great Topic
Anyone had any experience with an Asterisk server as a VMWare virtual machine? We use Asterisk in virtual machines for testing only, nothing in productions. We have been discussing production virtual Asterisk servers but have not tested yet. I would like to hear from anyone running multiple Asterisk Virtual Machines on one or more servers in production environment. Researching found that Asterisk will not work well in a virtual cluster OS implementation (multiple cluster nodes [think beowulf]) due to SIP stack issues, multi threading across multiple RAM resources. Can anyone shed some more light on why this is and is anyone trying to improve this? Thanks.
