Hi,
We have 3 Gateway servers -- CentOS 5.3 (non-graphical mode) +
Dansguardian
- Squid.
Not much traffic or load. We have 3 ISP & 3 separate teams using 1
ISP
each, hence we have setup 3 different servers.
I was wondering it it is possible to use virtualization and
consolidate
all
3 servers on single server.
yes you can. i guess only consideration might be having individual nic per isp and 1 for internal lan.
It can also be done with 2 NICs one for LAN and one for external; with bridge-utils to create tap interfaces which in turn are bound to the "external" NIC. In this specific case tap0 <> ISP0, tap1 <> ISP1 etc.
you can use vmware server if you like on linux as a host if you like
Or Linux KVM + userland kvm-qemu tools.

Hi
Most of the hosting companies offering Virtual Private Servers (VPS) seem to be using Parallels or ZEN. I rarely hear any other name.
Any particular reason why they do not use VMWare or VirtualBox or LinuxKVM.
Maybe LinuxKVM is too recent ..
I believe my virtualization server will be similar to the hosted VPS. Pls correct me if I am wrong here.
The only difference is that if all your VMs have the same OS and the same apps, maybe memory overcommit will work more efficiently. Better RAM utilisation ...
Do ZEN or Parallels offer some easy GUI or some other advantages ?
virt-manager and libvirt provide a consistent UI at least on RH/CentOS if installing a complete OS as Domain-0 - whether it is Xen or KVM...
