Not really for a regular user. It is /etc/zones/zonename.xml only visible from the global zone.

Sun took extra care to be sure there is no way to "escape" directly from the virtual machine (zone) into the controlling domain. That would create a horrible security hole. And some data must exist locally in kernel or zsched memory, which requires privileged access.

Use ssh - that reads directly from the global zone via a "proxy". I don't get your requirement for local access. Unless you are a programmer writing code and cannot access the global zone. If so, then if the mcap is absolutely required you will have to work with your sysadmin on that requirement. S/he may write some code for you or "place" a file just after boot time:

Code:

cp /etc/zones/*.xml /etc/zones/zonename/root/tmp/

Which is a small security issue, compared to granting users access. You would then see the file you need in /tmp. This does not accomodate the use of prctl to dynamically change zone resource control values during runtime.

Code:

grep 'mcap_physcap' /etc/zones/zonename.xml
<mcap physcap="34359738368"/>

so

Code:

mcap=$(ssh zonename "grep 'mcap_physcap' /etc/zones/${zonename}.xml" )

You can then parse the number in the variable mcap.
