The current timeout is set to only three seconds - and considering that vring_wait_reply() or rather get_second() is not doing any rounding, the real timeout is likely rather 2 seconds in most cases. When the host is really badly loaded, it's possible that we hit this timeout by mistake; it's even more likely if we run the guest in TCG mode instead of KVM. So let's increase the timeout to 30 seconds instead to ease this situation (30 seconds is also the timeout that is used by the Linux SCSI subsystem for example, so this seems to be a sane value for block IO timeout).

- SeaBIOS (bios.bin) is the successor of pc bios. See http://www.seabios.org/ for more information. - The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios project (http://www.nongnu.org/vgabios/). - The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is available at http://repo.or.cz/w/openhackware.git. - OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable firmware implementation. The goal is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) compliant firmware. The included images for PowerPC (for 32 and 64 bit PPC CPUs), Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built from OpenBIOS SVN revision 1280. - SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware implementation for certain IBM POWER hardware. The sources are at https://github.com/aik/SLOF, and the image currently in qemu is built from git tag qemu-slof-20171214. - sgabios (the Serial Graphics Adapter option ROM) provides a means for legacy x86 software to communicate with an attached serial console as if a video card were attached. The master sources reside in a subversion repository at http://sgabios.googlecode.com/svn/trunk. A git mirror is available at git://git.qemu.org/sgabios.git. - The PXE roms come from the iPXE project. Built with BANNER_TIME 0. Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping: 8086:100e -> pxe-e1000.rom 8086:1209 -> pxe-eepro100.rom 1050:0940 -> pxe-ne2k_pci.rom 1022:2000 -> pxe-pcnet.rom 10ec:8139 -> pxe-rtl8139.rom 1af4:1000 -> pxe-virtio.rom - The sources for the Alpha palcode image is available from: git://github.com/rth7680/qemu-palcode.git - The u-boot binary for e500 comes from the upstream denx u-boot project where it was compiled using the qemu-ppce500 target. A git mirror is available at: git://git.qemu.org/u-boot.git The hash used to compile the current version is: 2072e72 - Skiboot (https://github.com/open-power/skiboot/) is an OPAL (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can run an hypervisor OS or simply a host OS on the "baremetal" platform, also known as the PowerNV (Non-Virtualized) platform. - QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to provide virtualised drivers for PPC MacOS guests.
