Parallels Desktop 26.1 update adds a driverless version of Parallels Tools for Linux, using the in-kernel VirtIO to power guest and host system integrations.

Parallels Desktop Adds ‘Future-Proof Linux Compatibility’

I have a habit of creating virtual machines with small virtual hard disks. While doing some R&D work I create a VM with 25GB hard disk. I had totally abandoned it after using for few weeks. Yesterday I had to do some research on Adobe InDesign Server. After installing IDS it quickly took up all the space and I started getting low disk space warning.

Now was the time to do the inevitable, that is to resize the virtual hard disk.

I had done the drill previously as well and it was (or seemed) quick. I performed following steps:

1. Fire Hyper V MMC and select "Edit Disk" from Actions.

2. Select VHDX file to resize

3. Select Expand operation

4. Specify new size (52GB)

I happily fired the VM. But it still complained about the disk space which was same again (24.66GB).

After some thought I remembered that I missed a vital step. I had to attach the virtual hard disk in Disk Management Console and resize it. Following is what is needed to get bigger hard disk.

1. Open Disk Management Console (diskmgmt.msc) and select Attach VHD from Action menu.

It shows 24.66GB allocated for existing disk and 27GB of fresh space available for use.

2. Right click on existing hard disk and choose Extend Volume from menu.

3. Select all (or what ever you want to use) available space and click Next.

After rebooting into VM, you will get bigger hard disk.

All sub-domains to one IP in hosts file?

I’ve got a VirtualBox VM running with host-only networking. This VM is running Apache, and I want to setup a bunch of name-based virtual hosts in it that can be accessed from the web browser on the host machine.

The thing is, every time I add a new sub-domain for a virtual host, I have to add it to the hosts-file. Right now I have something like this:

Why VM snapshots are affecting performance?

I read in one of the VMware KB article says that snapshots will directly proportional to VM performance.

But my team keep asking me how snapshots can affect performance.

I would like to give them solid reason behind the statement that snapshots are performance killers.

Can any one explain a little bit theory behind why actually snapshots are affecting…

Suggestion for a simple LDAP server and client

Trying to set up a headless LDAP server on a linux virtual machine (vmware). Small scope, but needs to be reliable and easy to use. Strong preference for simplicity over features, command-line over gui.

What are some of the good options?

Also need some sort of client / manager utility for it so I can log in remotely, view the contents of the…

Number of logical processors per VM?

I have a server (quad core) running Windows Hyper-V Server 2008 R2 with two Windows Server 208 R2 Standard guest virtual machines.

I’ve noticed the number of logical processors setting (under the Processor) settings page for each VM defaults to 1, but allows me to choose anything from 1 to 4 “virtual processors” (or “logical processors” equivalently I…

Virtual Machine guest optimization tips

I’ve installed Windows7 in VirtualBox 2.2.4 and worked like a charm. But compared with my WindowsXP virtual machine, the performance is slow.

I’ve installed Windows7 in (non-virtual) machines and the performance was better than XP and Vista.

I would like to know about tips to optimize the guest Windows7 so the performance will be acceptable.

I was thinking…

VMWare ESXi, change the default path for a VM

For some reason VMWare ESXi has decided that one of my VMs is on a completely different path to the path it is actually on.

So my VM is on /vmfs/volumes/long-guid-here/my-vm-name but when I try to open it I get the message “File < unspecified filename> was not found.” Which is not really surprising as unspecified filenames are quite difficultto…
