1) Try restarting your mac, and trying to open the.DMG again. 2) Hold down the Control key when you click on the.dmg then select Open from the context menu. Theis should give you a window to 'allow anyway'. If neither of these options solves the probelm for.
I am running 5.0.10Ubuntur104061 on Ubuntu 15.10 x64. My guest OS is Windows 7 x64 with all patches. Maybe it's relevant: I just added discard='True' to my harddisk. After this, I had running the.
I had tried to install an OS named Veos with virtual box,but when I had finished the installation,I can not open the wirtual machine Veos,and I had this output: Failed to open image 'C:UsersTakfarinasVirtualBox VMsAristaFilesvEOS-lab-4.16.6M.vmdk' for writing due to wrong permissions (VERRVDIMAGEREADONLY).
Error:
Cannot register the hard disk ‘*.vdi’ {UUID_UUID_SAME} because a hard disk ‘*.vdi’ with UUID {UUID_SAME} already exists.
Cause:
OIM VirtualBox Hard Disk (.vdi file) with UUID {92957aa4-0f2b-4b4b-be1e-23db8e47393c} already exists, and trying to add another OPAM or OAM VirtualBox Hard Disk (.vdi file) with the same UUID {92957aa4-0f2b-4b4b-be1e-23db8e47393c}.
It is due to the fact that OIM VDI file was cloned or copied to be used as OPAM or OAM VDI.
Oracle VM VirtualBox is a program that allows you to create operating systems on virtual machines, i.e. To use Windows programs on Linux. If a program doesn't work under WINE, for example, it will probably work in its native environment, Windows. Hey, I'm trying to get this to boot the first time. After following the README directions it just hangs about 30 seconds into starting up. The last log lines when it hangs are shown below.
Solution:
Open ‘Command Prompt’ run as ‘Administrator’
cd C:Program FilesOracleVirtualBox
run the command: VBoxManage.exe internalcommands sethduuid “<Location of Existing Hard Disk>.vdi
Copy the newly changed UUID – 635c3815-d489-47fb-90ab-9b0400a323be
Open the .vbox file located at C:UsersrajesVirtualBox VMsOIMVBImage11.1.2.3
Replace old UUID with new UUID (from step 4) – <HardDisk uuid=”{635c3815-d489-47fb-90ab-9b0400a323be}”
Close the VirtualBox and open again, so that it can refer the new VDI UUID.
Add new VDI file, there will not be any error, as the conflict got resolved once you changed the UUID to new one.
I hope this question hasn't been asked already, but i certainly could not find it on the forum. I am trying to mount a .dmg file for my Snow Leopard 10.6.2 guest, but virtual box keeps giving me this error: Failed to open the CD/DVD image C:Users[..].dmg. Could not open the medium 'C:Users[..].dmg'. VD: error VERR_VD_DMG_INVALID_HEADER opening image file 'C:Users[..].dmg' (VERR_VD_DMG_INVALID_HEADER). Result Code: E_FAIL (0x80004005) Component: Medium Interface: IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd} Callee: IVirtualBox {c28be65f-1a8f-43b4-81f1-eb60cb516e66} I was able to mount a previous .dmg file successfully in virtualbox and it ran well in the Mac guest.
