This is fixed (as in, I added a test only) in: http://git.annexia.org/?p=virt-what.git;a=commitdiff;h=54b726fa7c9687b692162488e8934a426f9fa6c3 So I should note a few things. Firstly upstream virt-what did actually detect GCE just fine. It prints: # virt-what google_cloud GCE isn't KVM! It's their own thing. I suspect it might even be baremetal. However the version of virt-what in RHEL 9.0 is not very up to date and doesn't have this check. This was fixed by the rebase in RHEL 9.1 (bug 2074476). I upgraded your GCE instance to virt-what-1.22-1.el9.aarch64 and detection now works there. If a fix is required for RHEL 9.0 you will need to go through the usual z-stream steps.

[root@wshi-aarch64 ~]# virt-what google_cloud [root@wshi-aarch64 ~]# /usr/libexec/virt-what-cpuid-helper [root@wshi-aarch64 ~] [root@wshi-aarch64 ~]# rpm -q virt-what virt-what-1.22-1.el9.aarch64 But the dmesg command prints the next line: [ 0.000000] smccc: KVM: hypervisor services detected (0x00000000 0x00000000 0x00000000 0x00000003) So it seems like the hypervisor is KVM. Does /proc/device-tree/hypervisor/compatible exist and what does it contain? Because this is RHEL/aarch64, /proc/device-tree doesn't exist at all. Because it's aarch64 there is no CPUID (or equivalent?) I'm not sure if there is a good equivalent way to find out if KVM is being used underneath on RHEL/aarch64. Fixed in: http://git.annexia.org/?p=virt-what.git;a=commitdiff;h=da3568b25a582603ba15690793c8867cc7c5d2a8 Note that we now print the following, because this *is* KVM-based: # virt-what google_cloud kvm Tested on GCE aarch64 env: [root@wshi-aarch64 cloud-user]# virt-what google_cloud kvm [root@wshi-aarch64 cloud-user]# rpm -q virt-what virt-what-1.22-2.el9.aarch64 Verified this bug per comments 16 and 17.

Description of problem: subscription-manager has a requirement to offer automatic registration requirements in major cloud providers. Currently, we deliver `cloud-what` to determine which cloud a system is on to attempt a auto-registration for a given host. Our tooling also looks for input from virt-what to determine facts that are used for entitlements, and this auto-registration process (sub-man facts -> virt.{host_type,is_guest}). virt.host_type is defined with the output of `virt-what`. In the process of testing subscription-manager auto-registration in GCE, it was found that virt-what returns nothing on ARM systems in GCE. In my testing, there is information that indicates it is a KVM system, but not in the ways looked for by virt-what. This issue will prevent automatic registration from working in GCE for ARM systems. Version-Release number of selected component (if applicable): virt-what-1.21-2.el9.2.aarch64 How reproducible: 100% Steps to Reproduce: 1. Deploy RHEL 9 in GCE on aarch64 2. `virt-what` Actual results: [root@r9-arm facts]# virt-what;echo $? 0 Expected results: $ virt-what kvm (if another valid new value is added, we will need to update code as well afaik) Additional info: Will attach dmidecode output and subscription-manager facts below: [root@r9-arm ~]# dmidecode # dmidecode 3.3 Getting SMBIOS data from sysfs.
