[Kimchi-devel] [PATCH 0/4] Live migration backend: additional features

*** REQUIRES THE FOLLOWING PATCH TO APPLY ***
'Live migration backend: non-shared storage VM migration'

This patchset implements the remaining features of the
live migration backend to be shipped in Kimchi 2.0:

- password-less root setup: if provided with a user/password that
has SUDO ALL access in the remote host, the backend will
set the password-less environment automatically. 
    
- added same remote hypervisor verification
    
- added same remote architecture verification
    
- (ppc64 only): if applicable, verify subcores-per-core


This is the usage after this patchset:

- migrating a VM without any credentials: if the password
less root login isn't set, it will simply abort the operation:

$ curl -k -u user  -H "Content-Type: application/json" -H "Accept: application/json" "https://localhost:8001/plugins/kimchi/vms/<vm_name>/migrate"  -X POST -d '{"remote_host":"a_remote_host" }'


- migrating a vm with credentials: same thing as above,
but will set up the password less root login if it's not
set yet:

$ curl -k -u root  -H "Content-Type: application/json" -H "Accept: application/json" "https://localhost:8001/plugins/kimchi/vms/<vm_name>/migrate"  -X POST -d '{"remote_host":"a_remote_host", "user":"a_sudoall_user", "password":"passwd_of_user" }'

Note that 'sudoall_user' can be the root of the remote host. 


*** NOTE ***
First patch is a change in WoK necessary to make the
'user' and 'password' fields optional.
