Ошибка 1006 noVNC соединения к виртуальной машине Proxmox VE

Неспешно знакомлюсь с системой виртуализации ProxMox VE, которая примечательна тем, что из коробки поддерживает одновременно KVM и OpenVZ. И, помимо этого, при крайне простом веб-интерфейсе, поддерживает все фичи виртуализации KVM в бесплатном режиме, хотя и выкидывает, при каждом заходе в админку, уведомление “у вас отсутствует подписка”. Что разительно отличает данную систему от VMware ESXi, которая в бесплатном режиме держит всего один камень, а также требует, как минимум, 2IP для создания виртуальной фермы серверов, ибо один забирает под сервер и не имеет собственной реализации NAT.

Всем удобная система, но напоролся на отвратительный баг, по которому в Mozilla Firefox с завидным постоянством отваливается браузерная noVNC консоль доступа к виртуальной машине через веб-консоль управления. Соединение просто прекращается, показывает форму логина и выдает ошибку Server disconnected (code: 1006). Причем наглухо, так что приходится скакать с бубном, пытаясь реанимировать noVNC соединение, ибо все новые начинают запускаться с этой же ошибкой.

Что только не ковырял, но лечится это только путем удаления куков для урла вебморды ProxMox и перечиткой сертификата, находящегося в разделе Дополнительно -> Сертификаты -> Просмотр сертификатов -> Серверы -> PVE Cluster Manager CA

Но поскольку noVNC консоль висла каждые пару минут, то стал искать пути как с этим жить и что делать, ибо в Vivaldi оказались те же проблемы. И случайно обнаружил очень занятный ценебаг-цефич: у меня установлена Mozilla Aurora, еще со времен протечки памяти Firefox. И вот при запуске Aurora стартует тот же самый Firefox 50.1.0, просто вторым окном. Но из него noVNC соединение работает вообще без нареканий, а из первого окна, где постоянно отваливалось – теперь максимум что, может зависнуть сессия noVNC, которую просто закрываешь и стартуешь новую консоль.

Очень странно конечно, но не менее странно, чем отвал сертификата ProxMox в процессе работы.

Еще одним вариантом быстрого доступа к консоли виртуальной машины с проблемами noVNC, является использование протокола SPICE (Simple Protocol for Independent Computing Environments) созданного как раз для доступа к десктопным VE машинам. В винде уже имеется встроенный виндовый клиент доступа RemoteViewer, но лучше установить свежий родной клиент. Тем более что там же можно взять драйвер редиректа USB.

Для использования SPICE соединения, следует погасить виртуальную машину, после чего в управлении виртуальной машиной PROXMOX, драйвер дисплея виртуальной машины надо переключить в SPICE режим, как показано на картинке. После старта виртуалки можно запускать соединение, либо с помощью виндового Remote Viewer, либо дополнительно установленного VirtViewer – последний работает как то по-стабильней.

З.Ы в процессе поиска решения, нашел самый угарный коммент о том, что чел обнаружил на своем сервере виртуализации установленный netcat6, который и выдавал эту ошибку. После того как он запустил команду “apt-get remove netcat6″ у него отлично заработало novnc. Если кто не понял, то повторять не надо.

[SOLVED] Promox 6: problem with noVNC — failed to connect to server

hermelin

Active Member

after upgrade to Promox 6, I have probem with noVNC console from webbrowser (Chrome,Firefox tested). After some time I cannot connect noVNC console to VM with error «failed to connect to server». After shutdown and start of VM everything work ok — for some time. Same problem is on VM with linux and Windows. This behaviour is at random for different VM. Some VM with noVNC works, other doesn’t working, at the moment.

Thanks for help

I execute this and not resolve.

I reboot server, but the problem persist.

I write this command and show me this now:

apt list | grep novnc-pve

VNC Client Access

Contents

Standard Console Access

As default Proxmox provides access via [noVNC] and/or SPICE and it is recommended to use this access whenever possible. If there are some reasons to have browser independent access it is possible to use an ordinary VNC client.

Enabling Access from other VNC clients

It is possible to enable the VNC access for use with usual VNC clients as RealVNC, TightVNC, Remmina etc.

Configure VNC Access via Monitor

1. Go to VM´s ‘Monitor’ panel in the web interface.
2. You can setup a plain VNC or also a password secured one:
   • for the plain one type the following into the monitor:

   100 denotes the port, this will get added to the VNC base port of 5900, so in this case the VNC server listens on all addresses on port 6000.

   • for the password secured one type the following into the monitor:

   note: the first «password» parameter after the IP address mustn’t be replaced by a password but is the word «password» itself, this is just a boolean parameter telling QEMU that the server needs a password.

3. now you may connect via the ip address and port (6000 in the above example)

The configuration is not persistent, i.e. after the VM has been stopped and started again the above actions have to be repeated in order to enable VNC access via external client.

Configure VNC Access via Configuration File

• Add in the VM´s configuration file /etc/pve/local/qemu-server/ .conf a line which specifies the VNC display number as follows («77» in the example below):

The display number can be freely chosen, but each number must occur only once. VNC service listens then at port 5900+display_number. Note that connections via noVNC start using display number 0 consecutively therefore it´s recommended to use higher numbers in order to avoid conflicts.

• Connect from VNC client to Proxmox host ip address and port as specified (5977 in the above example)

Note: Using this method it not possible to set a VNC password.
