Hi,
same problem on Debian 11 (Bullseye)
Code: Select all
Failed to open a session for the virtual machine Win10Pro.
Failed to load R0 module /usr/lib/virtualbox/VBoxDDR0.r0: Unable to locate imported symbol 'memset' for module 'VBoxDDR0.r0' (VERR_SYMBOL_NOT_FOUND).
Failed to load ring-0 module 'VBoxDDR0.r0' for device 'pci' (VERR_SYMBOL_NOT_FOUND).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
[EDIT #1]
As suggested above, I replaced the file /usr/lib/virtualbox/VBoxDDR0.r0 installed by version 6.1.34 with that provided by version 6.1.32, extracted from package virtualbox-6.1_6.1.32-149290~Debian~bullseye_amd64.deb
All my VMs seem to be working.
I waiting for a new version with the fix.
[EDIT #2]
As suggested by @galitsyn, I unistalled the deb package of version 6.1.34 and reinstalled VirtualBox using the VirtualBox-6.1.34-150636-Linux_amd64.run installer.
