NetBSD amd64当前版平台OpenBSD作为domu的尝试

[leo]

有关软件设置请参考 http://gobsd.org/showthread.php?t=2176 这个帖子，在这里不再详述了。
目前存在的问题：
1. 暂时没有考虑设置多核CPU
2. 网速有问题，系统提示：watchdog timeout
配置文件：

代码: 全选

kernel = '/usr/pkg/lib/xen/boot/hvmloader'
builder = 'hvm'
memory = '1024'
device_model='/usr/pkg/libexec/qemu-dm'
 
disk = [ 'file:/home/ob.gobsd,ioemu:hda,w',
'file:/home/i386.iso,ioemu:hdb:cdrom,r', ]
 
# Hostname
name = "ob"
 
vif = [ 'type=ioemu, bridge=bridge0' ]
 
boot= 'c'
pae=0
acpi=0
apic=0
 
vnc = 1
 
usbdevice = 'tablet' # Helps with mouse pointer positioning

需要禁用apic,acpi,pae?
网络性能极差，启动后屡屡显示错误

代码: 全选

re0: watchdog timeout

，有时无法用dhcp的方式获取网卡IP。
修改配置文件为：

代码: 全选

kernel = '/usr/pkg/lib/xen/boot/hvmloader'
builder = 'hvm'
memory = '1024'
device_model='/usr/pkg/libexec/qemu-dm'
 
disk = [ 'file:/home/ob.gobsd,ioemu:hda,w',
'file:/home/i386.iso,ioemu:hdb:cdrom,r', ]
 
# Hostname
name = "ob"
 
vif = [ 'mac=00:16:3e:57:9d:3d, bridge=bridge0' ]
 
boot= 'c'
pae=0
acpi=0
apic=0
 
vnc = 1
 
usbdevice = 'tablet' # Helps with mouse pointer positioning

也就是设置为固定MAC地址，启动后可以获取网卡，但是仍然网速奇慢，详附件xen-2-2.png

目前还尝试过的方式是在系统启动出现提示符后键入

代码: 全选

boot> boot hd0a:/bsd -c

，进入UKC模式，然后禁用apic,acpi和usb:

代码: 全选

UKC> disable apic
UKC> disable acpi
UKC> disable usb
UKC> quit

但是，这样设置方式也无效，网速依然是很慢。
有关watchdog的显示请参阅附件里xen3-1.png的图示。

网上查阅的，还有人提议这样：

代码: 全选

config -ef /bsd
UKC> disable mpbios
UKC> quit

但是测试后无效。

希望与其他进行过类似测试的朋友共同探讨。下面是OpenBSD的dmesg

代码: 全选

待摸索。

又尝试了在dom0的设置里加入了nolapic，还是不能解决watchdog timeout的问题，有点难度。

[lionux]

更新下当前版吧。最近更新了这个不知道会不会与watchdog timeout有关。

更新下当前版吧。最近更新了这个不知道会不会与watchdog timeout有关。

昨天更新为当前，现在系统无法启动了，回到了USB无法识别的问题，此外这个watchdog发生在domU的OpenBSD里，要更新是OpenBSD更新才对，感觉与NetBSD关系不大。
