It appears that the IBM developers in Boeblingen are actually working on something like that. Recent updates to the development trees on the git390 git server have been mentioning an "HVC": commit 0eb652d08e6f7aeec9e879a297aa1c9b7423f445 Author: Hendrik Brueckner <[EMAIL PROTECTED]> [S390] s390/hvc_console: z/VM IUCV hypervisor console support This patch introduces a new hypervisor console (HVC) back-end that provides terminal access over the z/VM inter-user communication vehicle (IUCV). The z/VM IUCV communication is independent of the regular tcp/ip network and allows access even if there is no network connection between two z/VM guest virtual machines. The z/VM IUCV hypervisor console back-end helps the user to access a z/VM guest virtual machine that lacks of network connectivity; and thus, provides a "full-screen" terminal alternative to 3215/3270 terminal sessions. Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of HVC terminals using a z/VM IUCV back-end. A recent version of the s390-tools package is required to establish a terminal connection to a z/VM IUCV hypervisor console back-end. It's not upstream yet, but I imagine it will be in the not too distant future. Mark Post
