(fixed on FreeSBIE 1.1.) -and you have to wait a bit for dhclient to do its thing; traffic to -address 10.0.2.2 is routed to 127.1 on the host. -- expect timer problems when guest kernel HZ is > hosts, -for example time sleep 1 takes 49 seconds and booting sleeps for -minutes at the acd0 probe with a FreeSBIE 1.0 guest, thats because -its kernel is built with HZ=5000, and FreeBSD's default is 100... -(no longer a problem with FreeSBIE 1.1.) The linux 2.6 kernel uses -1000 by default btw (changed to 250 recently). Enabling /dev/rtc doesn't -seem to help either (not included since it needs a patch to emulators/rtc.) -- using physical media doesn't work on 4.x hosts (missing DIOCGMEDIASIZE -ioctl.) -- the -smb option (smb-export local dir to guest) needs the net/samba3 -port/package installed in addition to qemu. -- RELENG_6 and up guests often crash while accessing the emulated cdrom -(see kern/84102, http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/84102), -using a kernel without PREEMPTION has been reported to fix this problem. -(or do an ftp install instead of installing from the emulated cdrom, and -then make a new kernel.) [fixed since 6.0-R.] -- 6.0-RC1 was released with an ed driver that doesn't like qemu's emulated -RTL8029 nic, this has been fixed in the meantime but if for some reason -you need to use that version as a guest you can temporarily add the patch -in this message: http://docs.freebsd.org/cgi/mid.cgi?200510131428.21211.jkim -(not included in the port since the used VIA VT86C926 PCI ID does not -really match the emulated nic exactly, it just `happens' to work with -6.0-RC1's driver.) -- if you want to use usb devices connected to the host in the guest -(usb_add host:... monitor command) you need to make sure the host isn't -claiming them, e.g. for umass devices (like memory sticks or external -harddrives) make sure umass isn't in the kernel (you can then still load it -as a kld when needed), 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. -- to avoid panics or non-working re(4) nics with FreeBSD guests if you -use qemu -net nic,model=rtl8139 -net user or tap ... enable the emulated -rtl8139 timer by building the port with RTL8139_TIMER enabled. -(the rtl8139c+ that model=rtl8139 emulates needs less cpu than qemu's -default ne2k nic which is driven by ed(4), it has not been made default -only because it may not work with all guests yet.) -- 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. You can build the port with -CDROM_DMA disabled to disable it. -- if you build qemu wihout SDL and then get crashes running it try -passing it -nographic. This should probably be default in that case... -- slirp (-net user) seems to be broken on recent -current, if this affects -you please use tuntap for now.

Scott Robbins posted a tap howto for --current here: - http://forums.bsdnexus.com/viewtopic.php?id=1563 -- qemu now uses aio at least for ide dma, so if you get `Bad system call' -crashes that is because aio is not (kld)loaded. -==== |
