Don't forget to adjust device node permissions in + /etc/devfs.rules. + +- Expect timer problems when guest kernel HZ is > hosts. The linux 2.6 + kernel uses 1000 by default btw. (changed to 250 later, and recent linux + kernels now no longer have a fixed HZ, aka `tickless kernel'...) + Enabling /dev/rtc doesn't seem to help either (not included since it needs + a patch to emulators/rtc.) + +- The -smb option (smb-export local dir to guest using the default + slirp networking) needs the samba port/package installed + in addition to qemu. (SAMBA knob.) + +- If you want to use usb devices connected to the host in the guest + yot can use usbredir over the network (see below); also unless you are + running qemu as root you then need to fix permissions for /dev/ugen* + device nodes: if you are on 5.x or later (devfs) put a rule in + /etc/devfs.rules, activate it in /etc/rc.conf and run /etc/rc.d/devfs + restart. Example devfs.rules: + + [ugen_ruleset=20] + add path 'ugen*' mode 660 group operator + + corresponding rc.conf line: + + devfs_system_ruleset="ugen_ruleset" + +- Still usb: since the hub is no longer attached to the uchi controller and + the wakeup mechanism, resume interrupt is not implemented yet linux guests + will suspend the bus, i.e. they wont see devices usb_add'ed after its + (linux') uhci module got loaded. Workaround: either add devices before + linux loads the module or rmmod and modprobe it afterwards. [Not sure + if this still applies to the new libusb host code used on recent + 10-current.] + +- If you get repeated `atapi_poll called!' console messages with FreeBSD + guests or other weird cdrom problems then thats probably because the guest + has atapicam loaded, which for reasons still to be determined has problems + with qemu's now by default enabled cdrom dma.
