csuhas32 Én a magam oldalán leakadtam egy működőképes bridge beállításán, hogy tudjon nyomtatni az a nyominger VM. 🙂
Emiatt fájlmegosztásig még nem jutottam.
Én úgy okoskodom, hogy egy windows-os VM is tudhatja csatolni és írni a "lemezt", szóval guest oldalon ott nem kéne, hogy uid/gid komoly szerepet játsszon. De lehet, hogy tévedek.
Most egy picit előreugrottam oda itt a Mintes VM-mel.
Mivel eleve más úton indultam (itt a VM user session-ben megy), most szembesülnöm kellett vele, hogy a VirtioFS nem támogatott ebben a felállásban.
"unsupported configuration: virtiofs is not yet supported in session mode"
Sikerült viszont virtio-9p eszközzel hozzáadni, bármit is jelentsen ez.
Úgyhogy én még nem írtam az fstabba semmit, csak cstoltam:
mount -t 9p -o trans=virtio dok /mnt -oversion=9p2000.L,posixacl,msize=104857600
Innen merítettem:
https://wiki.qemu.org/Documentation/9psetup
A "dok" a "dokumentumok" könyvtáram a ~ alat.
Csatolás után létrehoztam itt egy teszt könyvtárat (ez a guesten van):
root@kl-Standard-PC-Q35-ICH9-2009:/mnt# ls -l |grep teszt
drwxr-xr-x 2 root root 4096 aug 16 17:29 teszt
Ez meg a hoston:
laco@DellG3:~/Dokumentumok$ ls -l |grep teszt
drwx------ 2 laco laco 4096 aug 16 17.29 teszt
laco@DellG3:~/Dokumentumok$ id -u
1001
Látszik, hogy létrehozáskor valahol átfordul a tulajdonlás, bár átjönnek a meglévő gid/uid adatok.
Szerk.: ez kicsit zavarosnak tűnik visszaolvasva. Szóval a guesten:
root@kl-Standard-PC-Q35-ICH9-2009:/mnt# ls -l xmouse*
-rwxrwx--- 1 1001 1001 90335 jan 7 2019 xmouse.png
root@kl-Standard-PC-Q35-ICH9-2009:/mnt#
Tehát ott az 1001:1001, ami a hoston lévő userem uid/gid-je.
Nekem sem teljesen világos még...
Annyi bizonyos, hogy a hoston a guest az én nevem alatt fut:
