Subject: virsh: Don't generate invalid XML in attach-disk command
X-Git-Tag: v0.9.11.4~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=73908b1d1045ed7e0cb4298e6a7f3f5fdfd1a386;p=thirdparty%2Flibvirt.git

virsh: Don't generate invalid XML in attach-disk command

The attach-disk command used with parameter --cache created an invalid
XML snippet as the beginning of the <driver> element was not printed
when used solely with --cache and no other attribute to driver.
(cherry picked from commit 5b4740265cf1e9cd00165e54e1f5e81f9008bc63)
