PS нету тега virtiofs, ок использую virtio
Следую инструкциям
https://virtio-fs.gitlab.io/howto-windows.html
https://libvirt.org/kbase/virtiofs.html
По итогу в windows появляется диск, проброшенный с хоста.
Полазить по диску можно, создать директорию можно.
Но стоит начать что-то копировать, не важно в каком направлении, win гость выплёвывает ошибку ввода вывода и диск отваливается. При этом я явно вижу, что один файл скопировался. Т.е. возможно оно виснет на моменте попытки установить права на файл.
В логах windows добрался до сообщения «virtiofs.exe appcrash» без подробностей. И правда, если перезапустить службу, диск опять появляется в госте.
При этом на стороне хоста я не вижу каких либо ошибок.
Есть у кого-то истории успеха? Или идеи куда смотреть?
Хост Linux flotsky-pc 5.18.12-3-MANJARO (да, давно не обновлялся)
Гость w10 pro
qemu запускается от пользователя libvirt-qemu
Пробрасываемая директория на хосте имеет права 755 и пользователя/группу libvirt-qemu
