Почему может не работать бридж для kvm?

hint000, спасибо за ответ!
по tcpdump -i eno2 port 67 or port 68 тишина. Значит трафик из виртуалки не выходит...

Как убедиться в безопасности блока питания для домашнего сервера?

1. Практически NoName, наклеек нету на нём
2. Не обжигает, слегка тёплый
3. Да, контакт с заземлением, но в квартире проводка без заземления...
Спасибо!

Как убедиться в безопасности блока питания для домашнего сервера?

Moskus, большое спасибо!

Как убедиться в безопасности блока питания для домашнего сервера?

Moskus, скорее фантазии. Хочу подстраховаться.

Доска с версиями сервисов?

Спасибо!

Какой дистрибутив Linux выбрать для повседневной работы?

Аналогично. После долгих поисков вернулся на Mint + Cinnamon, очень доволен.

Управление Windows ПК без AD?

Спасибо, инструмент именно такого плана и ищу.

Управление Windows ПК без AD?

Командная строка, powershell + psexec мы используем, а вот некой GUI утилиты для этого нету. Смотрел в сторону Windows Intune, но пока не применял на практике. Кажется этот продукт как раз подходит для среды, где удалённые пк работают без включения в домен.

Управление Windows ПК без AD?

Антон, он подходит, да. Но у нас несколько сотен пк по всей России, там где они стоят не подразумевается установка контроллеров домена.

Гипервизор на Linux?

fdroid, сервер настоящий. И это единственный сервер для разработки, основательно переделывать его не дадут.

Гипервизор на Linux?

Proxmox вроде для Debian-like, у меня Centos.

Activemq Successfully connected to tcp в логах?

Алексей Черемисин, спасибо! Действительно, debug логи помогли. Судя по всему, не верно настроен failover на самих брокерах:

Спасибо большое! Посмотрим настройки на стороне брокеров.
