Two questions about NVDIMM devices
Hi, I've met two situations with NVDIMM support in libvirt where I'm not sure all the parties (libvirt & I) do the things correctly. The first problem is with memory alignment and size changes. In addition to the size changes applied to NVDIMMs by QEMU, libvirt also makes some NVDIMM size changes for better alignments, in qemuDomainMemoryDeviceAlignSize. This can lead to the size

Emulated TPM devices and snapshots of running VMs
Hi, I would like to clarify how to make snapshots of running VMs with emulated TPM devices. As far as I understand QEMU documentation, it's possible to make snapshots of running VMs with TPM, but it's important to retain the state of swtpm. Does libvirt assist with that in any way or is it completely user's responsibility? libvirt pauses the VM internally when making a snapshot,
