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. /Jason

RE: Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization
Agreed, I run 2 LBed tomcats in seperate vmware machines for our dev environ. with no noticeable problems. Depends on the app though. For instance, my mysql cluster in vmware sucks when you do just about anything in the vm machines, because it's so sensitive to latency. -Tony Sent from my Windows Mobile® phone. -Original Message- From: Alan Chaney Sent: Wednesday, February 18, 2009 1:26 PM To: Tomcat Users List Subject: Re: Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization I agree with Jorge - I run several Tomcats under VMware for both production and development.

Re: Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization
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. Regards Alan Chaney Jorge Medina wrote: 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.

RE: Apache Tom Cat in a VM as VMWARE or Red Hat Virtualization
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. -Original Message- From: acacio costa [mailto:acaciofco...@yahoo.com.br] Sent: Wednesday, February 18, 2009 2:33 PM To: users@tomcat.apache.org Subject: 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.
