*** Bug 1855364 has been marked as a duplicate of this bug. *** Bulk update - Move RHEL-AV bugs to RHEL After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. The bug issue still exists. Steps: Red Hat Virtualization Manager Web Administration Software Version:4.5.2.1-0.1.el8ev RHV node: vdsm-4.50.1.4-1.el8ev.x86_64 libvirt-8.0.0-10.module+el8.7.0+16047+746a126c.x86_64 kernel-4.18.0-416.el8.x86_64 qemu-kvm-6.2.0-18.module+el8.7.0+15999+d24f860e.x86_64 1. Prepare a running VM with TPM device enabled. 2. Left-click the VM and then right-click and select 'Create Snapshot' 3. Keep the default setting in the popup 'Create Snapshot' window, and fill the name into the 'Description', then click 'OK'. Test result: Failed to create snapshot with checking 'Saving memory'. """ Operation Canceled Error while executing action: test-tpm: Cannot create Snapshot. VM has a TPM device attached. """ And I have noticed that this bug has been closed automatically, and do you plan to fix it, thanks. As this RFE hasn't been implemented by the platform, RHV won't support this feature. Hi Peter, Could you help have a look at the previous comments, thanks? BR, juzhou. Hi junqin, I asked Jaroslav and Michal for helping evaluating. RHV won't use it, CNV might not be interested in memory snapshots yet. And for migration: live-migration is about having the swtpm state on a shared disk and there are some issues with locking the state files. So no need to fix it currently. Please just regard the error you encountered as expected. Thank you!

Milan, we migrate VMs with TPM while the swtpm state is not placed on a shared disk, no?

Yes, swtpm data is stored on a local file system and the transfer is handled transparently by libvirt. After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. |
