This from the newer kernel package, but I doubt this configuration has been changed in the openSUSE kernel:
susi:~ # grep PARAVIRT /boot/config-4.0.0-rc4-1.g126fc64-desktop CONFIG_PARAVIRT=y # CONFIG_PARAVIRT_DEBUG is not set # CONFIG_PARAVIRT_SPINLOCKS is not set # CONFIG_PARAVIRT_TIME_ACCOUNTING is not set CONFIG_PARAVIRT_CLOCK=y
So yes, PARAVIRT is enabled.
