Hi,
It is caused by the memory parameter. I lowered the domain1 memory to 32M
and it seems succeeded now. I haven't been able to connect to it. But
that's a different problem. When I try to create domain2 with 16384k, the
problem appears again.
This is the memory parameters I use:
My total physical mem = 128M
domain 0 = 64M
domain 1 = 32M
I knew I can't use 100% of physical memory. Learned that a few days ago
when creating domain0. So I choose to create domain 2 with 16M, and it failed.
64 + 32 + 16 = 112 < 128
It should let me create it. Is there a bug?
[root@oscan18 root]# xenctl script -f/etc/xen-mynewdom
Domain defaults:
name XenoLinux2
size 16384
vifs 1
domainImage /boot/xenolinux.gz
domainInitRD null
rootDevice /dev/hda5
rootArgs rw
usrDevice null
NWIP 169.254.1.0+
NWGW 169.254.1.0
NWMask 255.255.0.0
MaxDomainNumber 1000
NWNFSServer 169.254.1.0
NWNFSRoot null
XIToolsDir /usr/local/bin/
args init=/linuxrc 4 DOMID=+
Failed to create domain using: /usr/local/bin/xi_create 16384 XenoLinux2
[root@oscan18 root]# xenctl domain list
id: 0 (Domain-0)
processor: 0
has cpu: true
state: 0 running
mcu advance: 10
total pages: 16383
id: 1 (XenoLinux2)
processor: 0
has cpu: false
state: 8 suspended
mcu advance: 10
total pages: 8192
Then I tried to use 8M for domain2, it succeed.
Yesterday I used domain0=96M and domain1=16M and it also failed.
96+16=112 < 128M
Anyone else has experience on this?
Thanks all for your help!
sincerely,
Ning
