[xenpreview-dev] initial vm creation reports "not enough free memory" and xm info returns error "int exceeds XML-RPC limits"

[Krysan, Susan]

Our server is now configured as 32 processors with 32GB RAM and some virtual machines are running, so xm info | grep -i memory shows:

total_memory           : 130943
free_memory            : 126572
max_free_memory        : 126888
max_para_memory        : 126884
max_hvm_memory         : 126578

Krysan,

  can you do this you server?

machine:~ # xm info | grep -i memory
total_memory           : 8959
free_memory            : 0
max_free_memory        : 2513
max_para_memory        : 2509
max_hvm_memory
