I didn't see what are the main differences in
http://libguestfs.org/guestfs.3.html#backend
Specifically, I'm interested in what is faster (direct sounds faster to
me), and if there are any major restrictions (networking?)
Here's an example command we are running (sorry, Python'ish, but you'll get
it):
['virt-sysprep', '--connect', 'qemu:///system', '-a',
u'/zram/3.6/images/lago_basic_suite_3_6_engine_root.qcow2',
'--selinux-relabel', '--hostname', 'lago_basic_suite_3_6_engine',
'--root-password', 'password:123456', '--mkdir', '/root/.ssh', '--chmod',
'0700:/root/.ssh', '--upload',
'/zram/3.6/id_rsa.pub:/root/.ssh/authorized_keys', '--run-command', 'chown
root.root /root/.ssh/authorized_keys', '--mkdir', '/etc/iscsi', '--chmod',
'0755:/etc/iscsi', '--write',
'/etc/iscsi/initiatorname.iscsi:InitiatorName=iqn.2014-07.org.lago:lago_basic_suite_3_6_engine',
'--mkdir', '/etc/selinux', '--chmod', '0755:/etc/selinux', '--write',
'/etc/selinux/config:SELINUX=enforcing\nSELINUXTYPE=targeted\n', '--mkdir',
'/etc/sysconfig/network-scripts', '--chmod',
'0755:/etc/sysconfig/network-scripts', '--write',
'/etc/sysconfig/network-scripts/ifcfg-eth0:HWADDR="54:52:c0:a8:c8:03"\nBOOTPROTO="dhcp"\nTYPE="Ethernet"\nONBOOT="yes"\nNAME="eth0"']
TIA,
Y.
