The third release candidate for Xen 3.0.5 is now available at Quite a few issues are fixed: 32-bit PV-on-HVM on 64-bit hypervisor, virtual framebuffer setup, HVM ioemu and rombios issues, to name a few. I would like the next release candidate to be a *realistic* candidate for release — hence it is absolutely bug fixes only from here on to reduce churn, and we need as much testing as possible to make -rc4 a good one. We’re getting close!
