System z kernel features – z/VM

•

AF_IUCV Protocol Support (kernel 2.6.21)

•

Enables IUCV communication via the BSD socket interface between Linux VM

guest or between a Linux guest and CMS

•

TTY terminal server over IUCV (> kernel 2.6.27)

•

Provide central access to the Linux console for the different guests of a z/VM.

•

The terminal server connects to the different guests over IUCV.

•

The IUCV based console is ASCII based.

•

Fullscreen applications like vi are usable on the console.

•

Support for enhanced z/VM DASD IUDs (> kernel 2.6.26)

•

When z/VM provides two virtual devices (minidisks) that reside on the same

real device, both will receive the configuration data from the real device and

thus get the same uid. To fix this problem, z/VM provides an additional

configuration data record that allows to distinguish between minidisks.

•

z/VM APAR VM64273 needs be installed to enable enhanced DASD IUDs.
