当 nova 尝试启动时，我遇到了以下问题。

/usr/local/bin/nova-compute --config-file /etc/nova/nova.conf
cloud@CloudServer:/opt/stack/devstack$ /usr/local/bin/nova-compute --config-file /etc/nova/nova.conf

确保文件 ../stack/nova/openstack-common.conf 有一个 entry
module=processutils
几天前 entry
module=log
已从 openstack-common.conf 中删除
，同时我得到：-
n-cpu 屏幕日志导入错误 - 从 nova.openstack.common 导入日志
同时我在 openstack-common.conf 中看不到您需要的条目。
请回复 larsks 的建议是否对您有用。

看起来您正在使用nova-compute-flex驱动程序，它既不是 (a) 官方 OpenStack 项目，也不是 (b) 默认包含在devstack.

查看错误：

TRACE nova.virt.driver     from nova import processutils
TRACE nova.virt.driver ImportError: cannot import name processutils

这似乎是 flex 驱动程序中的一个错误。如果你看，例如，ncflex/nova/virt/flex/volumes.py你会看到：

from nova.openstack.common import processutils

这很好用。有可能修改vifs.py为替换：

from nova import processutils

和：

from nova.openstack.common import processutils

将修复该错误，尽管这看起来很容易发现，我希望您会发现其他问题。
