Re: installing FreeBSD in VMWare-player
I could solve the boot problem of the USB key in the older laptop of my wife by inserting into /boot/loader.conf the line kern.cam.scsi_delay=1 (note: set kern.cam.boot_delay did not help) matthias -- Matthias Apitz «...una sola vez, que es cuanto basta si se trata de verdades definitivas.» «...only once, which is enough if it has todo with definite truth.» José Saramago, Historia del Cerca de Lisboa ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: installing FreeBSD in VMWare-player
I wrote a small howTo for such a migration for others in the same situation. Comments/Impromvements are welcome; Thanks matthias $Id: moveFreeBSDintoVM.txt,v 1.2 2010/09/02 10:55:29 guru Exp $ How to move a complete FreeBSD installation into a VM Matthias Apitz g...@unixarea.de 1. Preparations in the running FreeBSD system Save the current FreeBSD partition layout to paper, i.e. print: - /etc/fstab - output of 'df -kh' - output of 'bsdlabel ad8s4' (or whatever your disk is) so you later know the sizes you will need in the new VM. Reboot the system to single user mode, run fsck(8) in all file systems and mount them read only, while staying single user. Do dump(8) of all the partitions to some external media you later can use in the VM a) physically and b) could be mounted in FreeBSD. I used an USB disk with an UFS file system on it as /dev/da0s1a: # mount -t ufs /dev/da0s1a /mnt # dump -0au -f /mnt/usr.dump /usr # dump -0au -f /mnt/var.dump /var # dump -0au -f /mnt/root.dump / Finally shutdown the system. 2. Prepare the VM Attach resources big enough to reflect your real system to the VM. I used: RAM: 2 GByte IDE: 164 GByte (as one file in the host) Make sure that the VM's boot order is: 1st CD/DVD, 2nd disk, so you later can easy decide from where to boot by just attaching or not the CD/DVD to the VM, even if the disk has already a MBR. Copy an ISO image of the so called FreeBSD livefs to the host and attach this as CD/DVD to the VM 3. Partitioning of the disk This part is a bit tricky because the FreeBSD livefs does not really guide through it. Boot from FreeBSD livefs and - define country and keyboard - run standard installation from the menu - fdisk(8) the disk, use entire disk for FreeBSD - let it install FreeBSD's boot manager - partition the slice to the layout of your old system, i.e. to the following result: /dev/ad0s1a1 GByte / /dev/ad0s1b4 GByte swap /dev/ad0s1d2 GByte /var /dev/ad0s1e6 GByte /tmp /dev/ad0s1f(rest 146 GByte)/usr - commit the last chance before scribbling on disk The installer will now do the real fdisk(8) and BSD-label of the partitions. It will newfs(8) the above file system and try to install FreeBSD in it, which is not on the CD/DVD and which is not what we want. Answer all questions as NO to get finally back to the main menu of sysinstall(8) tool. Reboot again into the FreeBSD livefs and go to the fixit repair mode menu, start a shell. The above mentioned file systems are created fine and even the boot manager is fine in place (ofc it would not find anything to boot). The file systems are already polluted which things we don't want (because we later will restore from dumps). Run newfs(8) in all file system devices again: # newfs -m 0 -o space /dev/ad0s1a # newfs -m 0 -o space /dev/ad0s1b # newfs -m 0 -o space /dev/ad0s1d # newfs -m 0 -o space /dev/ad0s1e # newfs -m 0 -o space /dev/ad0s1f We now have clean file systems (and boot manager installed). 4. Restore the dumps First restore the old root file system using the booted FreeBSD livefs, mount the new root as /mnt and the USB disk containing the dumps as /usb: # mount /dev/ad0s1a /mnt # mkdir /usb # mount -t usf -o ro /dev/da0s1a /usb # cd /mnt # restore rf /usb/root.dump # cd / # umount /mnt One could as well restore the other dumps the same way, but it's better to see if the new root file system already boot fine, because restoring the /usr dump will take many hours (in my case 9 hours for 120 GByte), Reset the VM (no need to worry, nothing is mounted), detach the CD/DVD and reboot the old/new root file system into single user mode. Remount the /root writable and restore the /usr dump: # mount -o rw / # mount -t usf -o ro /dev/da0s1a /mnt # mount /dev/ad0s1f /usr # cd /usr # restore rf /mnt/usr.dump (after 9 hours) # mount /dev/ad0s1d /var # cd /var # restore rf /mnt/var.dump Check and edit the /etc/fstab to reflect the new device names (in my original system the disk was /dev/ad0s8 and not /dev/ad0s1). Make /tmp writable for all users # mount /dev/ad0s1e /tmp # chmod 1777 /tmp The system is now installed and should be boot up fine to normal multi user mode, just reboot normally. 5. Final changes Edit some system files to reflect the new VM environment: /etc/rc.conf: - network interface is now em0, and not wlan0 /boot/loader.conf - sound (still not working) /etc/X11/xorg.conf - recreate the X11 config file the normal way install the vmware-tools for FreeBSD (still pending) 6. Some notes about performance The host is Dell Precision M4400 with Dual Core CPU of 3.09 GHz and runs Windows 7 Professional. It took 9h to restore a dump of /usr which was produced in ~2h.

The man page of restore(8) reads about creating pristine file system, made by newfs(8). Later, in the VM environment, I'd like to have only one big file system... Is it possible to restore the tree dumps into one big file system or do I have to rebuild the same slicing as I now have? You won't have to rebuild the slicing. Just create the relevant directories in your big file system, cd into them and use restore. Will it be a problem having the kernel /boot/* in this case far away from the beginning of the partition? I did some 1st tests with installing FreeBSD into a VM. I grabed some other laptop which runs already Win7 and installed a VMWare-player in it to do some tests. Of course the VMWare-player was not able to boot from a prepared USB key. A workaround was a boot from some ISO image of a boot manger (I used plpbt-5.0.10.zip from http://www.plop.at/) which allows you to choose the USB storage as boot device after 1st stage boot. The system comes up fine from the USB key and I created a 160 GByte slice with the standard procedure like: # fdisk -I /dev/ad0 # fdisk -B /dev/ad0 # bsdlabel -w ad0s1 auto # bsdlabel -B ad0s1 edit the disk label and change partition a from unused to 4.2BSD as partition type: # setenv EDITOR /usr/bin/vi # bsdlabel -e ad0s1 create the future root-filesystem on it and mount it to /mnt for the installation: # newfs -m 0 -o space /dev/ad0s1a # mount /dev/ad0s1a /mnt install freebsd into /mnt; this assumes that you have the kernel and userland in /usr/src and /usr/obj ready to be installed; # cd /usr/src # make installworld DESTDIR=/mnt The 'make installworld' failed with errors in the Makefiles (...); for example the file /usr/src/lib/libc/uuid/Makefile.inc had a line like this: SRCS+? uuid_compare.c uuid_create.c uuid_create_nil.c uuid_equal.c \ uuid_from_stringc uuid_hash.c uuid_is_nil.c uuid_stream.# \ uuid_to_string.c where it should have: SRCS+= uuid_compare.c uuid_create.c uuid_create_nil.c uuid_equal.c \ uuid_from_string.c uuid_hash.c uuid_is_nil.c uuid_stream.c \ uuid_to_string.c (note the ? singn and the # sign), i.e. the content was broken and some other files were missing in the /usr/src tree of the USB key. I used the same key last year to install from it the system to my netbook EeePC and it worked like it should. Since then the USB key was unused and carried around in the bag of my laptop.
