Установка ВМ по VNC на XenServer

Раньше я писал о том, как это сделать, но вот нашел способ лучше:

Исходник: https://habrahabr.ru/sandbox/48567/

Для подключения к консоли свежесозданной виртуальной машины используется VNC:

• выясним текущий номер домена для VM:
  
  xe vm-param-list uuid=[VM uuid] | grep dom-id
  
  
• выясним порт vnc для этого домена:
  
  xenstore-read /local/domain/[domain]/console/vnc-port
  
  
• удаленное подключение:
  
  vncviewer -via root@[xenserver] localhost:[port]
  в качестве [port] используются последние две цифры полученного порта

Citrix XenServer 7.0.0 host pool eject ERROR (The SR.shared flag cannot be set to false while the SR remains connected to multiple hosts)

Итак, есть пул на XenServer 7.0
При попытке извлечь хост из пула получаем ошибку:

Информативно grep bucardo.log

Часто нужно видеть, что добавляется в bucardo.log на ходу. А добавляется туда куча всякого мусора, особенно когда процесс репликации длительный.

Пользуюсь такой командой:

tail -f bucardo.log | grep -E 'delta count|COPY|chunk|Finished|Pushdelta|bucardo_track'

или такой:

tail -f bucardo.log | grep -v ' MCP ' | grep -v ' CTL '

или такой tail -f bucardo.log | grep ' KID ' | grep -v 'Got a notice for'

Вывод выглядит так:
