First of all, let me say I’m not at all a security expert. As gpg key creation is using /dev/random as random number generator, it is as secure on a virtual machine, as on a real machine. /dev/random is a blocking device, and will stop delivering any randomness beyond the available amount. You can check … Read more
VirtualBox can run 64-bit guests on a 32-bit host. You’ll need to make sure your processor has hardware virtualization and that it is enabled in the BIOS. You can find some extra information at the VirtualBox Forums
You can safely reduce the time down, but you may run into issues with inproperly closed connections on networks with packet loss or jitter. I wouldn’t start tuning at 1 second, start at 15-30 and work your way down. Also, you really need to fix your application. RFC 1185 has a good explanation in section … Read more
At this time, there is no way to rename a VM. You could try this as a workaround: Delete the VM while retaining all the Disks that were attached to it. Then recreate the VM with the new name and reattach the Disks that were attached to the original VM.
Storage folks refer to VMs as I/O blenders. This is because all of the guest’s files are typically inside of a “container” like a VMDK. This VMDK is a single file that contains all other files used by the VM. Consider that an 80GB VMDK might not have all block allocated sequentially on the disk … Read more
This VMware guide on virtual to physical machine migrations should be a good start, though it looks like you’re required to use 3rd party tools like Sysprep and Symantec Ghost. PlateSpin makes a commercial tool called PowerConvert that does both Physical-to-Virtual and Virtual-to-Physical conversions.
I believe this should do it for a virtual hard drive. VBoxManage modifyvm winxp-web-dev –hda “/home/vbox/.VirtualBox/HardDisks/my_new_disk.vdi” (That is how I do it when I create vm’s from the console)
If you are using classic deployment, basically all you have to do is: Sysprep your server (Windows) or deprovision the agent (Linux) Hit Capture using the portal to create an image of your VM Use Azcopy to copy the VHD file generated to the secondary region Create new image (secondary region) using the VHD file … Read more
In general, no, unless you meet one of two very specific constraints. Either: The device needs to be exposed read-only (this MUST be at the device level, not the filesystem level) to all the VMs, and MUST NOT be written to from anywhere at runtime. or: The volume must be formatted using a cluster-aware filesystem, … Read more
The linked clone works similar to the snapshot technique. Snapshots work in a way that saves disk use: When you create a snapshot and make changes after this (as you work with the system inside the VM), VMware stores only the changed parts of the disk (sectors). Linked VM clones work similar: If you have … Read more
