you can, but they won’t work:) in 4.3 the whole q35 is tech preview, with bugs we’ve fixed in 4.4. custom emulated machine is really just for the cases where you can troubleshoot by trying a “similar enough” machine type. using a different chipset or type from different major version will likely just fail on vm start. > Any deeper information about implications? > What is the "Default" value for Bios Type? i440fx with seabios(Legacy BIOS) > > Did anything change in 4.3.8 (eg official support for q35)? no, only in 4.4 where q35/seabios becomes the new default for new 4.4 clusters > > I search also through official docs for RHV 4.3 (virtual mgmt guide, appendix > A), but for example I don't find any reference to the "Bios Type" parameter > and a vague reference to the "Custom Emulated Machine".
