[Xen-ia64-devel] [PATCH] Improve error message when HVM domain creation failed

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

Currently, when VHPT or vTLB are not able to allocate to HVM 
domain, the xm create command shows the following error message 
because the return value of vmx_final_setup_guest() is -1(EPREM).

# xm create /xen/HVMdomain.1
Using config file "/xen/HVMdomain.1".
Error: (1, 'Operation not permitted')


This patch changes the return value of the following functions 
to -12(ENOMEM). Therefore the error message is changed to 
"Cannot allocate memory". 

 - vmx_final_setup_guest()
 - init_domain_tlb()
 - init_domain_vhpt()

# xm create /xen/HVMdomain.1
Using config file "/xen/HVMdomain.1".
Error: (12, 'Cannot allocate memory')

Best regards,
 Kan
