aspierssean-k-mooney, kashyap: ugh, I think we need to rethink this whole machine type / capabilities thing :-(18:15
aspiersjust spent most of today (yes, Saturday) trying to get to grips with it18:15
aspiersthe problem is that currently we're only calling libvirt's getDomainCapabilities once per architecture, with the assumption that covering a single machine type (the default) for that architecture is enough18:18
aspiershowever, the default for x86_64 is 'pc', but we need domain capabilities for 'q35' in order to boot SEV guests18:19
aspiersso for x86_64, we need domain capabilities for at least two machine types: 'pc' and 'q35'18:20
aspiershowever the good news is that I've realised we can get a sensibly small list of machine types to call it with by looking for the 'canonical' attribute in machine types returned from getCapabilities (N.B. not getDomainCapabilities)18:21
aspierse.g. getCapabilities returns these:18:21
aspiers<machine canonical='pc-i440fx-2.11' maxCpus='255'>pc</machine>18:21
aspiers<machine canonical='pc-q35-2.11' maxCpus='288'>q35</machine>18:22
aspiersso my proposal is to change get_domain_capabilities to call the API once per canonical machine type, rather than just with the default machine type18:23
aspiersand I've already enhanced config.py so that it can extract these canonical machine types from the capabilities XML18:23
*** betherly has joined #openstack-nova18:24
aspiersmy only remaining concerns are a) that you might disagree this is a good idea for some reason I missed, and b) what if the canonical machine types returned by getCapabilities don't include the default machine type for this arch, or they don't include the default machine type specified by CONF.libvirt.hw_machine_type?18:25
*** ralonsoh has joined #openstack-nova18:25
aspiersmaybe we need to call the API for the canonical machine types *and* whatever utils.get_default_machine_type() returns (if different)18:26
aspiersthat should cover every eventuality18:26
aspiersanyway, not expecting a reply at the weekend :) I just wanted to do a braindump while this is still fresh in my mind18:26
aspiersI think I'll continue along these lines and just hope that you agree it's the right way18:27
