Hi all.
When libvirt creates an OpenVZ machine, it does smth like
# vzctl create $ctid --ostemplate `ostemplate`
And we can't specify an --config `config` argument. In this case vzctl chooses
a default config file (a value of CONFIG variable from /etc/vz/vz.conf).
But there are cases when we want to specify a config file directly, as in
# vzctl create $ctid --ostemplate `ostemplate` --config `config`
I think, that we can try to use the same `ostemplate` name as --config value, if corresponding template exists,
i.e., if there is a file /etc/vz/conf/ve-`ostemplate`.conf-sample, libvirt will run a command
# vzctl create $ctid --ostemplate `ostemplate` --config `ostemplate`
Otherwise, it will run it's default command
# vzctl create $ctid --ostemplate `ostemplate`
(the same arguments.)

Example of creating a machine with nondefault config:
1. Create /etc/vz/conf/ve-altlinux-test.conf-sample
2. Create /var/lib/vz/template/cache/altlinux-test.tar
3. Use libvirt with (hypothetical) XML:
<domain type="openvz">
<name>100</name>
<memory>1</memory>
<os><type>exe</type></os>
<devices>
<filesystem type="template">
<source name="altlinux-test"/>
<target dir="/"/>
</filesystem>
</devices>
</domain>
-----------
Example of creating a machine with default config:
1. Ensure there is no /etc/vz/conf/ve-altlinux-test.conf-sample
2. Create /var/lib/vz/template/cache/altlinux-test.tar
3. Use libvirt with (the same as above) XML file
