So there's also the series from Andrew to allow Solaris to boot without resorting to use the 'msr_relaxed' option: https://lore.kernel.org/xen-devel/[email protected]/ This has been R-A: https://lore.kernel.org/xen-devel/[email protected]/ But AFAICT it's missing a repost with some minimal adjustments? If we don't get this in we should document on the release notes that Solaris guests will likely require 'msr_relaxed=1' option added to the configuration file in order to work. Thanks, Roger.
