QEMU Google Summer of Code 2026 project report

Four Google Summer of Code 2026 contributors worked on QEMU projects over a 12-week internship. Aadeshveer Singh implemented fast snapshot loading using QEMU's postcopy migration infrastructure and Linux userfaultfd(2), so RAM pages are populated on demand, and testing showed a major speed up. Tanish Desai added x86 PCID support to COCONUT-SVSM for confidential VMs, including a bitmap allocator for the 4,096 available PCIDs. Nicola Ramacciotti implemented the Observability and Configuration Protocol in COCONUT-SVSM plus a Linux driver and svsm-tools utility. uchouT added USB device redirection to qemu-rdp via usb-redir and URBDRC.
