RE: [Xen-users] What are your bottomneck in using Xen solution?

[Nathan Eisenberg <nathan@xxxxxxxxxxxxxxxx>]

In a well engineered system, all of these factors should become a bottleneck at 
the same time.  

In reality, network is often a limitation for me, as I rarely deploy Xen 
servers with local storage - I prefer to use iSCSI shared storage because the 
ability to migrate a domain is very useful.  This means that storage is 
attached via 1Gbps or multiple 1Gbps ports.

CPU, RAM, and disk are all cheap.  10Gbps ethernet is not - yet.

Thank You,

Hello,

Given that nowadays standard Dual Quad Core server is such popular,
with Dual GB Ethernet, bundles of high capacity of SATA disks running
as RAID 10.

What are the factors that prevent you from installing additional VM on
an existing server?


e.g.

1. CPU
2. Memory
3. Disk I/O
4. Network
5. Else?
