This should be:

Requirements = $(REQUIREMENTS) && (Name =!= LastRemoteHost)

Since LastRemoteHost includes the "vmN@" prefix, but Machine doesn't.

If you want to avoid all VMs on the last machine, this should work:

Requirements = $(REQUIREMENTS) && (stringListMember(Machine, LastRemoteHost, "@") =!= TRUE)

Look for match_list_length in the condor_submit man page for a hint on
how this might be extended to a short list of previous hosts.

Match_List_Length = 3
Requirements = $(REQUIREMENTS) && (Name =!= LastMatchName0) && (Name =!= LastMatchName1) && (Name =!= LastMatchName2)
