Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization
Hi,
Does anyone use Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization?
i apreciate to know if you have issues and a tips to go on.
Other things to know, Performance comparative with a real server? as the same? better?
What the parameters you perceive as better than other environment and what cause as you move Tom Cat to VM.
Thanks in advance,
Acacio Costa

not a VMWare expert but I found there is a significant boost in Networking connectivity with NAT over Host only ..(please email offline as this is O/T for Tomcat..)
Thanks
Martin

Tell that to Citrix? They made revenues of about $620M last year almost
entirely based on Xen technology.
Still only a fraction of VMWare's t/o, though. ($1,9B)

Isn't xen basically dead? Or have rumors about its demise been greatly
exaggerated? I thought everyone was moving to kvm.

I admin a fairly large deployment of tomcats on vmware server and now have
started to move to xen as well and the only thing i can say is that if your
application is IO intensive then you might notice slower performance
vmware/xen unless you use block devices.
For anything else, if you provision your VM with the same specs as a
physical machine that you will compare it to then you should hardly notice
any difference at all.

I would add only that You - OP - might want to have a "Bridged"
network connection in the VM. I have VmWare Fusion on my Mac and as
soon as I bridged it things got much better, network wise.

I agree with Jorge - I run several Tomcats under VMware for both
production and development.
However it is worth noting that if you use the appropriate vmware tools
for your installation (vmware-guestd etc.) you get a significant
performance boost on network accesses which may well be important for
tomcat. (See vmxnet) YMMV.

There are no issues on running Tomcat in a VM. Tomcat is unaware of where it is running.
Performance depends on the host running your VM. If you compare a VM running application A on host H compared to application A running directly on host H, you will notice that running on the real server is faster. This is true for any application, not just Tomcat.

FYI, it's "Tomcat".

I've run Tomcat under VMware for testing purposes. No issues, it's
no different than running it on a different host.
FWIW,
