7.在用户生成证书时报如下错误：
在SUSEsp2:~/key # nova-manage project zipfile –project=mycloud –user=kevin –file=nova.zip
Stderr: “Using configuration from ./openssl.cnf\nerror loading the config file ‘./openssl.cnf’\n15649:error:02001002:system library:fopen:No such file or directory:bss_file.c:126:fopen(‘./openssl.cnf’,'rb’)\n15649:error:2006D080:BIO routines:BIO_new_file:no such file:bss_file.c:129:\n15649:error:0E078072:configuration file routines:DEF_LOAD:no such file:conf_def.c:197:\n”
The above error may show that the certificate db has not been created.
Please create a database by running a nova-cert server on this host.
解决方法：
susesp2:~/key # zypper install openstack-nova-cert
susesp2:~/key # /etc/init.d/openstack-nova-cert start
susesp2:~/key # chkconfig openstack-nova-cert on
8.在使用nova查看虚拟实例时出现400错误：
susesp2:~/key # nova image-list
ERROR: n/a (HTTP 400)
解决方法：
susesp2:~ # zypper search nova-api
Loading repository data…
Reading installed packages…
S | Name | Summary | Type
–+——————–+——————————–+——–
| openstack-nova-api | OpenStack Compute API services | package
susesp2:~ # zypper install openstack-nova-api
其它问题引起的http 400错误，novarc环境变量写错，这点很重要：
suse11sp2:~/user # cat novarc
NOVARC=$(readlink -f “${BASH_SOURCE:-${0}}” 2>/dev/null) ||
NOVARC=$(Python -c ‘import os,sys; print os.path.abspath(os.path.realpath(sys.argv[1]))’ “${BASH_SOURCE:-${0}}”)
