== DESCRIPTION ==<br />
<br />
<p style="margin-left:11%; margin-top: 1em">This low-level<br />
utility is used by [[Man/vzmigrate.8|<b>vzmigrate</b>(8)]] to check if a<br />
container can be succesfully restored on a destination<br />
system before performing live migration. Currently, it is<br />
able to check CPT version and CPU flags compatibility.</p><br />
<br />
<p style="margin-left:11%; margin-top: 1em">There are two<br />
modes of operation: to show a property and to test a<br />
property. Showing mode is invoked if a property specified<br />
with no arguments; testing mode requires one or many<br />
arguments after a property name. Generally, one runs<br />
<b>vzcptcheck</b> on one node to get a property, and on the<br />
other node to check for the property.</p><br />
<br />
<p style="margin-left:11%; margin-top: 1em">Note that this<br />
utility does not guarantee that migration will succeed even<br />
if all tests are passed. It merely gives a way to prevent<br />
migration which will definitely fail.</p><br />
<br />
== OPTIONS ==<br />

<br />
<p style="margin-left:11%;">To get CPU capabilities number,<br />
run <b>vzcptcheck caps</b> on the destination node. Then, to<br />
check if a CT can be migrated to node with such a CPU, run<br />
<b>vzcptcheck caps</b> <i>ctid capnum</i> on the source<br />
node.</p><br />
<br />
== EXIT STATUS ==<br />
<br />
<p style="margin-left:11%; margin-top: 1em">In showing<br />
mode, returns <b>0</b> upon success, or <b>1</b> in case of<br />
an error.</p><br />
<br />
<p style="margin-left:11%; margin-top: 1em">In testing<br />
mode, returns <b>0</b> if migration is possible (test<br />
passed), <b>1</b> in case of an error, or <b>2</b> if<br />
migration is not possible (test failed).</p><br />
<br />
== EXAMPLES ==<br />
<br />
<p style="margin-left:11%; margin-top: 1em">To check if a<br />
CT 123 can be migrated to $DEST, run the following commands<br />
on the source node. Note that error checking is omitted for<br />
brevity.</p><br />
<br />
<pre style="margin-left:11%; margin-top: 1em"> VEID=123<br />
VERSION=$(vzcptcheck version)<br />
echo Got CPT version: $VERSION<br />
ssh root@$DEST vzcptcheck version $VERSION<br />
echo Version check result: $?<br />
CAPS=$(ssh root@$DEST vzcptcheck caps)<br />
echo Got caps: $CAPS<br />
vzcptcheck caps $VEID $CAPS<br />
echo Caps check result: $?</pre><br />
<br />
<p style="margin-left:11%; margin-top: 1em">If both tests<br />
pass, you should get 0 as a result for both checks.</p><br />
