I have a 256 GB SSD 4 TB 5400 RPM HDD on my Windows 10 Pro machine. For my Hyper-V VMs, I put the storage on my 4 TB 5400 RPM HDD.
The VMs are super slow. I did a test and put the storage on my SSD and the VMs were super fast.
Is there anything I can do to speed it up when my VMs are on the HDD, or do I need to get a faster HDD?

I'm looking into one Proxmox server that is running out of space. It has some over provisioned storage. Everything looks to be fine except one VM disk. It is 10 GB disk according to configuration but the file itself on Proxmox is 15 GB big. I'm mostly using vmware and never seen such thing before.
Can someone tell why it is like that?
Is it the way Proxmox stores snapshots (this VM had one that was removed)? Or maybe it was resized?
I'm a bit worried for other VM disks.
Thanks a lot!
I had to migrate that disk to different storage. Disk file size become 10 GB big after this procedure.
Can I install openstack on 3 different virtual machines with the configurations as listed:
Controller Node: 1 processor, 4 GB memory, and 10 GB storage
Network Node: 1 processor, 4 GB memory, and 20 GB storage
Compute Node: 1 processor, 4 GB memory, and 30 GB storage
I wanted to know if having a physical machine with visualization enabled processor is essential for openstack deployment or one can proceed with virtual machines only. I am asking this because in almost all the documents i have read it suggests to have physical nodes.
I also want to know what difference will it make if i install on a virtual machine(assuming it is possible to install on a VM) & why can i not install openstack on virtual machines(assuming i cannot install openstack on virtual machines)
Please bear in mind that i dont want to install devstack.
I guess one can install controller and the neutron on VMs.
However, for the compute node you require a physical VM.
A simple configuration could be (as suggested in the openstack docs)
Controller Node: 1-2 CPU, 8GB RAM, 100GB Storage 1 NIC
Neutron Node: 1-2 CPU 2 GB RAM, 50 GB Storage 3 NIC
Compute Node: 2-4 CPU , 8GB RAM, 100+ GB Storage 2 NIC
However i guess(though unsure ) that the compute if has CPU virtualisation enabled, then the compute could also be a VM.
Someone who could specify the implications of running these nodes on a VM compared to physical nodes???
I bought a usb external drive and every time I try to copy to it I get lockup when 1.8 GB has been transferred and I can't cancel copy. Reboot required to clear it.
If I copy smaller chunks than 1.8 GB then it works and if I copy several smaller chunks, more than 1.8 GB in total is saved to usb disk no problem. It is only when I try to copy a folder with total of more than 1.8 GB that it fails at 1.8 GB of current transfer.
Running windows 7 64bit with USB2 ports and USB3 HGST Touro mobile pro 1TB external drive which is supposed to be usb 2 compliant. Drive formated using NTFS 4096 blocks size.
Any ideas why transfer would fail for anything bigger than 1.8 GB and is there anything I can do about it.
More hardware specs might help. For instance issues such have this have been observed on systems with NVIDIA USB EHCI chipsets: http://support.microsoft.com/kb/976972
I am working on a machine with an older intel CPU (core 2 duo 2.4 Ghz e6600) that doesn't have SLAT and doesn't support Hyper-V.
It is running Windows 8.1 (64 bit) with 4GBs of ram. What software options do I have if I wanted to run a virtual machine, in this case, another instance of Windows (ex. Win 7)?
Am I SOL? Will speed of VM be limited more by ram, cpu, or hard drive in this case?
Thanks,
i think your best option is VirtualBox form oracle, i use it becouse i have the same tipe of procesor, an work really fine for me, the only think you can only instala x86 OS, but anything else works fine.
some spec's for your virtual machines
Windows
Ram 1gb to 2gb, it is fine
procesor one core only
HDD 40gb it almos enough for you want todo (as developer i only use it for testing)
video dont use it unless you need it
linux/unix
Console only
ram 256MB to 512MB
procesor one core only
HDD 40gb it almos enough for you want todo
video is not need here
GUI mode
ram 512MB to 1gb(i recomend use 2gb if your plan to use Ubuntu)
procesor one core only
HDD 40gb it almos enough for you want todo
video dont use it unless you need it
hope help you
How much difference does dedicated graphics and HDD speed matter when using virtual machines?
For the last year I have been using a MacBook Pro 15" with the following specs with great success.
Core i7
8 GB RAM
7200 RPM HDD
Dedicated Graphics card (NVIDIA GeForce GT 330M 512 MB)
I do a good deal of development in Windows so I use VMware Fusion with Windows 7 and Windows Server 2008 as guest operating systems. Everything has worked really well.
Well, recently my wife's MacBook died and we got a replacement MacBook Pro 13" with the following specs
Core i7
8 GB RAM
5400 RPM HDD
Integrated graphics (Intel)
Since the processor and RAM are the same I thought I might benefit from the smaller form factor of the 13" MacBook (can use external monitor when at home) and my wife could use the power of the dedicated graphics for video editing and the like.
So that brings me to my question. How much will a slower HDD and non-dedicated graphics card effect my virtual machine performance? I don't play any games so I never thought I made use of the dedicated graphics card. I don't know if it actually helped with the VM or not. What about the Disk Drive speed? Does this play a major factor? I really never noticed any swapping when using VMWare Fusion. Thanks for any insight.
The difference will be negligable. You won't notice the graphics at all, and will barely notice the difference in speed from the hard drive.
Solid state disks are dropping in price all the time, if you do feel like the drive is "slow" down the track you can purchase an SSD and upgrade it yourself fairly easily without voiding your warranty. (OWC sell DIY SSD upgrade kits for example)
