Re: [HTCondor-users] VirtualBox: Guest user vs. Condor account!?!

[Rob <spamrefuse@xxxxxxxxx>]

Would this support for VMware Workstation also work with the free VMware Player?

Hi Rob -

I think a big part of the issue is most of the VM universe 
users/interest in the past has come from folks on Linux.  In addition, 
as the number of hypervisors has mushroomed, we started to leverage 
libvirt for HTCondor's VM universe implementation on Linux - but libvirt 
server is not available on Windows.  Also, most of the VM universe users 
we have worked with are moving away from vmware and towards KVM. Thus on 
Windows we need to pick and choose which hypervisors to support - we do 
not have enough effort at UW to support an entire array of hypervisors 
on Windows.  We are hoping to update VM universe on Windows to at least 
support current VMWare offerings - see ticket
  https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=740
Would that be helpful?  Have you tried out using the update Purdue 
posted here w/ VMware on Windows? If others in the open source community 
w/ software development skills are interested in adding support for 
others such as VirtualBox on Windows, let us know...

regards,
Todd
