[App_rpt-users] RPM's & Virtuozzo

Virtuozzo is the same as a VM (in purpose) but it doesn't work the same way
as VMWare. Virtuozzo natively installs the current version of Centos as an
"OS Package" when one creates a "container." This is why I asked about a RPM
or other means of installing core packages of Asterisks.

Virtuozzo is an integrated environment with the ability to "bounce" a
"container" to another "hardware node" in the event of a hardware failure,
such as a failing RAID. It has an integrated ability to do a scheduled
backup do a dedicated back-up server(s). Resources may be allocated at the
hardware node level or from a master control panel known as HSP. My network
sits behind a very capable hardware firewall with 100Mbps available at any
time.

I have a substantial investment in Virtuozzo. I have a dual processor
dedicated server with RAID sitting next to me capable of running Asterisks
on its own but on its own it doesn't have the ability to use a very strong
feature set of Virtuozzo. Virtualization is easy; integrated and managed
virtualization is a different story.

Hope you at least have employed a firewall such as via webmin.  Hackers are
likely to be targeting your box some day. Just saying from experience.

Doug

I would be extremely leery about the use of Crucial SSD?s.  While they have
been a strong product line in the past, their quality control of late has
translated into products that do not work.  Most recently they have been
accused of flooding the market with product that they know to be defective.
Buyer beware!

We got lured lured in by their defective product, and spent many wasted
hours, doing problem analysis and OS rebuilds.  When we dug in further
through research on the net, and confirmed what is printed above, we
abandoned Crucial and quickly moved to another product.

At our remote site we are using OCZ (x2) and SANDISK.  Both have been great
performers.

We are running Centos on all SSD?s. (DNS/Web/Mail, DSTAR and Allstar).

Greetings Group:

I am looking for the setting that will allow clipping off about 20mS of
radio received audio to prevent passing squelch burst onto the network.
Receiver in use has PL and COR gated logic to the URIx but for those users
without reverse burst PL radios, the noise burst is an issue.  

Thanks,

Couldn't you just install from CD into a VM?

or even
mount -o loop disk1.iso /mnt/point/

There are claims all over this list that acid/allstar/asterisk works 
fine in a VM.
