Здравствуйте!

2 машинки, debian etch, 2 одинаково собранных ядра,
со второй на первую он-лайн миграция работает, с первой на вторую нет.

Миграция же с HN-2 на HN-1 происходит абсолютно нормально. Все, кроме онлайн-миграции работают тоже нормально.

На всякий случай, приаттачил конфиг ядра, хотя, повторюсь, оба ядра собраны одинаково.

Модули соответствующие (vzcpt, vzrst) на обеих машинах подгружены?

По поводу квоты — вероятно, там не выключена квота, надо её выключить (vzquota off), предварительно убедившись, что никто там не стоит.

Здравствуйте,

А это проверили?

Еще можно попробовать loglevel повысить, скажем, до 10 (/etc/vz/vz.conf).

Все-таки, проверили ли вы причину сообщения?

Quote:

vzquota : (warning) Quota is running for id 103 already

исправив ее, по-прежнему миграция не работает?
