z/VM support for the Multiple Image Facility (MIF)

You can use z/VM® to define shared channel paths. For a summary of z/VM support of dynamic I/O configuration, see Table 1.

Table 1. z/VM dynamic I/O support for MIF and the coupling facility
z/VM Function	Release
z/VM Function	z/VM
Define shared channel paths?	Yes
Define coupling facility channel paths?	Yes (Note)
Write IOCDSs remotely?	No
Access I/O devices on shared channel paths?	Yes
Use software-only dynamic I/O?	Yes
Use hardware and software dynamic I/O?	Yes
Note: z/VM can define coupling facility channel paths for a z/OS® LP but does *not* support real coupling facility channel paths for use by z/VM or guest operating systems. z/VM does virtualize the coupling facility for guest test purposes.
