![]() ![]() Sharing the "Shared" folder won't allow access to "MyVM", even though they're on the same partition. The first could be lots of things, such as on a Windows host: "C:\MyVM" vs SecretCode wrote:write access to the machine folder Jul 2009, 10:20 Location: Finland Primary OS: Ubuntu other VBox Version: PUEL Guest OSses: Ubuntu, XP, other Is case 2 - shared access to a distinct subdirectory - safer? - Does the shared folder protocol restrict file read/write/deletes to within the specified subdirectory?

Is this a genuine, major risk (to the extent that you should never do this - I don't expect shared folders in VMs will ever be risk-free)? vdi files and snapshots all stored, as default, in "~/VIrtualBox VMs".Ĭase 1: A shared folder to the host's home dir "~" is set up, with read/write access.Ĭase 2: A shared folder to "~/Shared" on the host is set up, with read/write access. If the guest has write access to the machine folder, it could in principle delete critical files and corrupt/crash the vm.Įxample (I'm using Linux guests on a Linux host but I expect the answer does not depend on OS types): This must be a very common setup - if the host has only one drive or partition, shared folders will be on the same drive/partition. But I can't find any posts or pages about it now. I think I recall reading that there were major risks in giving a guest VM write access through a shared folder to the same partition that the virtual machine files (.vdi files, and/or snapshots, and/or.
