Description

I'd like to suggest that this issue be reconsidered. It recently came up on beaker-user-list that Beaker's inventory system currently reports LPAR systems with shared resources as not having a hypervisor. In the context of performance testing, this means that filters to request bare metal systems may come up with LPAR hosts running with access to shared resources, and hence the benchmark results may be affected by activity in other partitions on the same host. While I can understand an LPAR with a static resource assignment being considered "equivalent to bare metal", and hence not reporting a hypervisor, one running with shared resources is just as unreliable for benchmarking purposes as any VM running on KVM/Xen/VMWare/Hyper-V. We'll aim to address this issue directly in beaker-system-scan regardless (see bug 1132791), but that shared vs static distinction seems potentially relevant here as well. Gonna need access, or someone to send me a patch. Re-openning. It would still be useful to have ppc64 lpar detection built into virt-what, even if we (subscription-manager and entitlements) don't necessarily consider ppc64 lpar systems to count as virt guests. It would be easier to have that info and ignore it that to not have it at all. PowerKVM support also confuses that matter. Also, support for detection of ppc64 KVM and PowerKVM. virt-what-1.13 fails to detect KVM on ppc64. However systemd-detect-virt does. Created attachment 1116413 [details]
add ppc64 lpar and kvm detection to virt-what
This is based on the mailing list about the facts collected by subscription-manager for ppc64. This adds info about ppc64 virt modes to virt-what so subscription-manager will correctly the 'virt.is_guest' fact.
Note this makes a bit of an assumption, namely that ppc64 lpar guests are 'virt'.
My preference would be for virt-what to indicate a lpar guests, and include the
virt type. If RHSM/subscription-manager later need to special case ppc64/lpar to not count as 'virt', we can do that with the info available.
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.

Git patch
Verified with the packages: virt-what-1.13-7.el7.ppc64 Verify steps: 1. Prepare a RHEL system on LPAR. To find a ppc LAPR hardware on beaker, search condition is : System/Model contains LPAR And then schedule reservation and install rhel7.3. 2. # virt-what ibm_power-lpar_dedicated So verified.
