啟動nova時出錯

這裡需要修改python源**，將標紅處注釋掉。
linux-ffun:~ # vi /usr/lib/python2.7/site-packages/keyring/backends/gnome.py
import os
try:
from gi import repository
if repository.get_default().enumerate_versions('gnomekeyring'):
#gi.require_version('gnomekeyring', '1.0')
from gi.repository import gnomekeyring
except importerror:
補充1：
openstack安裝到這一步後，注釋掉那行**，再啟動還是可能會報錯，這個時候注意看nova.conf。這裡面有個my_ip不能寫死為hosts裡配置的controller。必須寫當前主機的ip位址，原因不明，注紅處是修改後的。
linux-ffun:/etc/nova # vi nova.conf

補充2：ml2_conf.ini檔案的flat_networks的值為oa
linux-ffun:/etc/neutron/plugins/ml2 # vi ml2_conf.ini
[ml2_type_flat]
flat_networks = oa
這個oa和介面設定有關。注意飄紅處
openstack報錯彙總
這段時間不是很忙 在做open stack的時候遇到的一些錯誤 我這裡用的是16g記憶體的pc機器建立虛擬機器做的實驗 所以報錯極多 1.在安裝open stack的時候突然飄紅 這裡報錯資訊是 error usr bin ntpdata 192.168.1.254 returned 1 inste...
openstack 熱遷移報錯
由於增加計算節點的記憶體容量，需要把某計算節點上例項全部遷移到其他節點，但是在遷移時，提示無法遷移 報錯如下 error nova.virt.libvirt.driver req ca51d7c1 e2b5 47dc a9fd 1a57363170c4 58f26a895b2b46759ee052c...
