Re: [ovirt-users] Python: Clone snapshot into VM
Hi,
a new version is available on github which supports a list of VM's in
the config.

Is it possible to clone a snapshot into a VM like from the web-interface?
The above workflow is a little bit resource expensive but it will when
it is finished make Online-Full-backups of VM's.

Re: [ovirt-users] Python: Clone snapshot into VM
Hi,
this was also an idea but with the single backup script you have the
advantage of backing up more than one VM at a time to speed up the
overall backup time and therefore to backup to different clusters and
different export domains.
But I will change the tool to set a list of VM's in the configuration to
cover both ways.
greetings

Looks really cool. Good job! What do you think of making the backing up
into a loop and fetching VMs from a list? My thinking is that you
usually have more than one VM you´d want to back up, so something like
this maybe:
def getVMsFromList(VMS_LIST):
try:
print 'Getting list of VMs from file \"%s\".' % (VMS_LIST)
fo = open(VMS_LIST)
output = []
for line in fo:
strippedline = line.strip('\r\n')
output.append(strippedline)
fo.close()
return output
except Exception as e:
print 'Exception in getting list of VMs:\n%s' % str(e)
exit(1)
And then you can loop:
for LIST_VM_NAME in getVMsFromList('VMs.list'):
Or to have the list of VMs in the config and then:
config = Config(config_file, debug)
VMS_LIST = vms_list
for LIST_VM_NAME in getVMsFromList(VMS_LIST):
