I've never dealt with VMWare until recently so I'm not familiar with it.
I think there's a few on the list that are.
I asked the admin at our data center to compile a new CentoOS 5 kernel
for one of our systems so that it would support a module I need for AVG.
He got it done, but it took him 5 hours to do it. He said half the time
was waiting for it to do its thing, the other half was actual work. He
did not compile the module I need (that's for me to do).
I've compiled many kernels and on the slower machines it takes about 20
minutes. Why does it take so long with a VMWare hosted virtual machine?
1) Did he preallocate the disk?
If that is a new image, the moment you start doing compiles you are
going to be expanding the disk if it isn't preallocated. Given that
compiles throw around a lot of small files, that's going to be really
inefficient.
2) Is VMWare doing checkpointing?
The system has to do some fairly intensive stuff if it is doing too much
checkpointing.
I'm about to run a FreeBSD kernel compile. I'll let you know how that goes.
