Hi,
I am taking my first steps towards virtualization.
I have 3 Gateway Servers; all on CentOS 5.3 (non-graphical mode) + Squid.
We have 3 separate teams each of 5-7 users who use 1 ISP each via
their own Gateway server.
I am keen to use virtualization and consolidate all 3 servers on a
single server.
I plan to install ZEN on a Pentium Core2Duo with 2GB RAM & 1 nic.
Then create 3 virtual servers and install Cents OS 5.3 (text mode) &
setup Squid etc.
Does ZEN support the following 2 features:
1. Sharing of a single physical NIC by multiple guest OSes with
individual IPs and Gateways.
Example:
Guest-1: ip=192.168.1.10, g/w=192.168.1.1
Guest-2: ip=192.168.1.11, g/w=192.168.1.2
and so on.....
2. Easy backup & portability of guest OSes.
Example-1: Easily copy Guest-1 backup from one ZEN server to
another ZEN server in case of h/w failure
Example-2: Easily backup Guest-1 backup to DVD or portable disk.
I appreciate any help to get myself started.
Thx
Sanjay

If you''re using Squid on the gateways in Reverse Proxy mode for caching content, consider using Varnish instead. While it''s not a distributed cache setup, it''s designed from the start to be a high performance threaded cache to put in front of your webservers. S.W.

I am using Squid as simple proxy for caching & internet sharing.

Just realized I have been spelling XEN as ZEN. Sincere apologies.
