No. You will need to create a pset with wanted cpu cores and alocate that to specific zone or zones to compliant as far as i recall.
Lets say for simplicity you have 10 zones, 1 global zone and 9 zones
9 zones have 1 vcpu share (including global), while 1 zone has 2 vcpu share.
This means that in only in the case of cpu pressure, say 100%, kernel will guarantee each zone 10% of resources (1 cpu share) and one zone (2 cpu shares) will get 20% of cpu resources.
Not cores per se, but compute power using FSS scheduler.
For instance, all zones are mostly idle using total of 10% cpu, any zone will able to use rest of cpu time, as long there is no competition for cpu time.
Only under cpu pressure the scheduler will kick in to alocate time per ratio (1:1:1:1:1:1:1:1:1:2 = 100) to ensure quality of service per shares configuration.
When using psets allocated to zones, a zone will have dedicated cores defined in pset and no other zone will able to use those cores.
And you will be compliant as oracle hard partition, if that didn't change in the meantime...
Hope that helps.

zcons(7D) Devices zcons(7D)
NAME
zcons - Zone console device driver
DESCRIPTION
The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global
zones.
Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave side is fronted
by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console.
The zcons driver is Sun Private, and may change in future releases.
FILES
/dev/zcons/<zonename>/masterconsole
Global zone master side console for zone <zonename>.
/dev/zcons/<zonename>/slaveconsole
Global zone slave side console for zone <zonename>.
/dev/zconsole
Non-global zone console (slave side).
