The error messages mention something about Transactional Memory (TM) and suggest that the host kernel doesn't support it for guests, which means I should disable HTM using cap-htm=off. - -First, I need to understand what's happening here. From the comments, it seems that when trying to start a virtual machine with Virt-manager, QEMU is throwing an error about KVM not supporting Transactional Memory on the host. This causes the installation or VM start to fail. - -Looking at the logs provided, Satheesh mentioned that they had a chat with Suraj, who explained that Power9 doesn't support HTM in guests right now. So any guest VM should be started with cap-htm=off. There's also a mention of a host kernel patch being worked on, which would fix this issue eventually. - -Another point is that libvirt isn't handling cap-htm yet; it doesn't set any defaults. So when starting the VM through libvirt, it might not pass the necessary flags to QEMU unless configured to do so. - -I see that some machine types like pseries-2.12 disable HTM by default, while others don't. If the current setup uses a different machine type (like pseries-bionic), it might require manually setting cap-htm=off or switching to a newer machine type that does this by default. - -So, what steps can I take to resolve this issue? - -1. **Check the Machine Type**: Determine which machine type my VM is using. If it's not pseries-2.12, maybe switching to that would help since HTM is off by default there. - -2. **Modify Libvirt Configuration**: Since libvirt doesn't handle cap-htm yet, I might need to modify the VM's configuration in libvirt XML files to include the cap-htm=off argument when starting QEMU. - -3. **Update Host Kernel**: If possible, apply the patch mentioned (https://www.spinics.net/lists/kvm-ppc/msg13378.html) to enable HTM support for guests on Power9. But this might be a future fix, not immediately available. - -4. **Pass cap-htm=off in CLI**: Alternatively, start the VM manually using the QEMU command line with cap-htm=off until libvirt is updated. - -I should also check if my current setup already uses pseries-2.12 or another machine type that supports disabling HTM by default. If not, changing the machine type might be necessary as an intermediate fix. - -Another thought: Perhaps Canonical needs to update their defaults for VMs so that by default, when using certain machine types on POWER9 hardware, cap-htm is set appropriately. Until then, manual configuration or applying patches might be required. - -In summary, the immediate fix seems to involve either changing the machine type to one where HTM is off by default (like pseries-2.12) or explicitly adding cap-htm=off to the QEMU command line when starting the VM through libvirt. -</think> - -To address the issue of KVM/QEMU installation failure on POWER9 hardware due to unsupported Transactional Memory (TM), follow these steps: - -### Immediate Solutions: - -1. **Check and Modify Machine Type:** - - Ensure your virtual machine uses the `pseries-2.12` machine type, which disables HTM by default. - - If using another machine type like `pseries-bionic`, modify it to `pseries-2.12`. - -2. **Update Libvirt Configuration:** - - Edit the VM's XML configuration in libvirt to include `<qemu:commandline><qemu:arg value='-cap-htm=off'/></qemu:commandline>`. - - This ensures cap-htm is disabled when starting the VM. - -3. **Start VM with QEMU CLI:** - - Temporarily start the VM manually using the command line, including `cap-htm=off` until libvirt is updated: - ```bash - virsh --connect qemu:///system create --config /path/to/vm.xml \ - --arg cap-htm=off - ``` - -### Future Considerations: - -- **Host Kernel Update:** Once the host kernel patch enabling HTM support for guests is available, update your kernel and re-enable cap-htm if needed. -- **Libvirt Update:** Monitor updates to libvirt that may automatically handle cap-htm settings based on hardware capabilities. - -By implementing these steps, you should resolve the installation failure due to unsupported TM and successfully run your VM on POWER9 hardware. \ No newline at end of file |
