Yes, the MAC address ranges that are used by virtual machines all over the world are reused. However, MAC addresses only need to be unique on the local layer 2 network. Anything on the other side of a router doesn't know or care what your local MAC addresses are. Only devices that are connected directly or through switches know each other's MAC addresses. ...

how are MAC addresses assigned to virtual machines They're made up. Oh, not completely; they use specific OUIs (the first 3 octets, sometimes called a vendor ID) to not conflict with known hardware vendors. But they're generated locally, there's no central database or anything like that. If it is assigned during creating a new virtual machine - ...

Typically, the virtualization platform will generate a new, random MAC address for each virtual network interface at creation (depending on the software, you might override that random MAC with one of your chosing). In the context of ethernet, a MAC addresses only have to be unique on a specific network segment to work so it's actually quite simple to ...

Docker is an application virtualisation tool. VirtualBox is a Virtual Machine tool. VB simulates an entire hardware environment whereas Docker isolates the reads/writes of the enclosed application from the rest of the OS. The overheads of a whole VM can be considerable whereas Docker apps don't need to replicate all of the OS so, in theory, you may be able ...

Do not install Hyper-V onto the same partition as your Windows 7. You want to use a separate partition for every Windows installation. I'm not even sure the installation routine would let you do that (in the next steps) Do you have a second machine to manage the Hyper-V Server with and RDP into the VMs? Otherwise it may make more sense to upgrade to ...

Of course it is. Install a legal copy of Mac OS onto VirtualBox, you can find here excellent instructions to do so. Make sure that the disk you are allocating to the VM is at least as large as the occupied part of your disk. Then install Guest Additions on the VM. This is a perfect time to make a full backup of your system, just in case anything goes ...

The answer should be complex, I hope not too much complicate, but more you read down more it is complex; for a large quantity of data I can suggest you the number 1 or the numbers 5 and 6: If you will not use at the same time both the virtual machines you can mount the same virtual disk to each of them: no need to copy. You can copy few (or more) lines or ...

There is, in fact, a limit on the number of drives exposed by Linux's abstract SCSI subsystem, which includes SATA and USB drives. This is because device files are marked by major/minor device number pairs, and the scheme allocated for the SCSI subsystem has this implicit limit. https://www.kernel.org/doc/Documentation/devices.txt The following major ...

The is hopefully no 32 bit restriction. x86 is to be taken as a generic term encompassing both x86 and x86-64 (a.k.a. amd64) architectures and opposed to architectures like SPARC, ARM, PA-RISC, Alpha, Power, Itanium and the likes.
