Hello,
 
I'm currently migrating a production application from older physical hardware, to a new vmware host.
 
I've confirmed that all components (java version, jboss version, application and  libraries) are the same between platforms.  I've also made the platforms  as close as possible, recognizing that vmware HD space, RAM and CPU are not the same as 'real' ones.  The remaining differences would be that our existing production server is (I think) some flavour of redhat running linux 2.6.8 on reiserfs, and the  new vmware host is ubuntu linux 2.6.24  using ext3. 
 
 I recognize that there's quite a difference between plain hardware  and VMWare hosts.  But...  
 
 When I start this application on my localhost (also ubuntu) for development it  takes about 17 seconds for the whole thing to start.  On production it  takes about the same.  But on the new VM host, it takes a minute and 17  seconds, and nearly the whole minute extra is experienced right here  (3rd line from bottom):

See how it takes nearly a minute after "Core system initialized" to proceed with the rest of the startup?
 
Has anyone seen this before, or have ideas what it could be, or where I should start looking for my lost minute?
 
Thanks.
