Re: problem about using xl create to start a domU

[Shannon Zhao <zhaoshenglong@huawei.com>]

Below is the output of xenstore-ls:

root@genericarmv8:/home# xenstore-ls -f
/tool = ""
/tool/xenstored = ""
/local = ""
/local/domain = ""
/local/domain/0 = ""
/local/domain/0/domid = "0"
/local/domain/0/name = "Domain-0"
/vm = ""
/libxl = ""

"ps -ef" prints:

root      1050     1  0 Jul10 ?        00:00:00
/usr/local/sbin/xenstored --pid-file /var/run/xenstored.pid

root      1135     1  0 Jul10 ?        00:00:00
/usr/local/sbin/xenconsoled --pid-file=/var/run/xenconsoled.pid
