OK, that's not really a migration - dead or alive - in zVM terms. Under zVM dead guest migration doesn't require the guest to logoff then logon under another hypervisor. We would still move their storage and configuration whether IPL'd or not. In this case I think you're saying have two configurations - one under KVM and another under zVM. Then manually co-ordinate the sharing or resources but ensure that you don't have both guests logged on simultaneously. > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO LINUX-390 or visit > INVALID URI REMOVED > u=http-3A__www2.marist.edu_htbin_wlvindex-3FLINUX-2D390&d=DwICaQ&c=jf_iaSHvJObTbx- > siA1ZOg&r=hsO4Lk6XlJWxPC1OayT7oG3wyw3H8GpACVStAsDQDSM&m=az6AjYLgWfcZrMl0ChAUXY9yxQl40O8NsLSRjQP90Co&s=mtLjWfIPT9equ2k8EPtiQpQMWrxnLGl0JNLT963UanA&e= > Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
