NetBSD 絹の日記

(https://wiki.netbsd.org/tutorials/how_to_set_up_a_guest_os_using_xen3/)

NetBSD/amd64 7.99.20 が入っている機械を xen にしようとした
しかし DOM0 kernel を 7.99.20 などから持って来ると panic する
そこで 7.0 の DOM0 を使って boot
pkgsrc から次の二つを入れておく
```
xentools42
xenkernels42
```

/boot.cfg にそれなりの設定をする

menu=Xen 7.0:load /netbsd-7.0-XEN3_DOM0.gz console=pc;multiboot /xen.gz dom0_mem=8192M

/etc/brconfig.bridge0 を設定

 h97@makoto 22:42:00/151005(~)% cat /etc/ifconfig.bridge0 
 create
 !brconfig $int add wm0 stp wm0 up

/usr/pkg/etc/xen/disk-h にそれなりの設定

kernel = "/export/NETBSD6/usr/INSTALL/kernel/netbsd-INSTALL_XEN3_DOMU.gz"
#kernel = "/netbsd-XEN3_DOMU"
memory = 1024
name = "disk-h"
#vcpus = 1
disk = [ 'phy:/dev/wd0h,0x03,w']
vif = [ 'bridge=bridge0' ]
#root = "/dev/wd0d"
root = "xbd0"

sudo xm create -c disk-h をすると、何だか止ってしまう

Using config file "/usr/pkg/etc/xen/disk-h".

Control ] で抜ける。

(xentools4*, xenkernel4*) は xm でなく xl を使うようになったような。
という訳で、僕は時代遅れ。要出直。
