![]() ![]() Press Win + R keys to open the Run dialog box, and then type OptionalFeatures.exe in it and hit Enter. To remove the conflict, you can try disabling Hyper-V. Some users noticed that the Hyper-V can interfere with the running of VirtualBox. It performs almost the same tasks as VirtualBox. Microsoft Hyper-V is a piece of virtualization program that enables users to create one or more virtual machines. If your operating system and processor are 64 bit, you can proceed with the following solutions. In the pop-up window, navigate to the Device specifications section and check the System type. Press Win + E keys to open the File Explorer, and then right-click This PC and select Properties. If you are using a 2 bit CPU, you will encounter the VirtualBox not showing 64 bit issue. The first thing you should do is to check if your computer has an 圆4 bit CPU. Now, let’s start fixing the issue! Method 1. iso file is invalid or a different kind, you may encounter the “VirtualBox not giving 64 bit option” problem. Besides, you should have a valid guest OS file that will be used to load the guest operating system. but I've leaned something.Read More How to Fix VirtualBox No 64 Bitīefore you fix the VirtualBox only 32 bit issue, make sure that you log in to your administrator account. even with the built-in Intel adapters.Īnyway. Network speed was nice and steady on both machines. Once I changed the numbers to be different on both cards. Never really paid too much attention to that setting, not fully knowing the consequences of keeping the same number (I had other reasons to keep the same number, on Windows installation. That's when it (finally) dawned on me that it HAD to be because I had the same MAC address on both cards, as defined on the Host. So once I finally got my hands on version 100, released on the as mentioned in the link above, the Code 10 went away (after reboot of the guest machine). Someone mentioned the bug here:įorums_virtualbox_org/viewtopic.php?f=2&t=65592 (again, due to me being new, I'm not posting the actual link) The main web page I found where the "latest drivers" were supposed to be, was actually pointing to an old version which had a bug resulting on that Code 10. ![]() The Code 10 was due to version 96 of the drivers. So all that messing around led me nowhere and that's how I, wrongfully (according to your comment now), concluded that this was just some Linux specific thing.īut if you have more info on this, I'd LOVE to give it a try!Īlright. That's when I Googled up KVM and found that it was just another Linux-specific solution. I followed the links on the KVM page, which led me to a Redhat website where I could download an ISO with the binaries for Windows. so I thought KVM was just some open-source project name for those drivers. Now, I wasn't familiar with KVM (I'm more of a Windows guy). From that link, I Googled "virtio-net", which led me to Virtio KVM. there really isn't much to work with there. ![]() but it's about "www_virtualbox_org/manual/ch06_html")Īs you can see. (ok, as a new member, I can't post a link. In fact, this is the documentation I found: ![]() The VirtualBox documentation I found on it was quite minimal. the whole "paravirtual" approach is pretty confusing to me. I thought buying dedicated NIC's would solve my problem. Note that on the Host machine, downloads don't seem to be significantly affected by the number of running VM. However, as soon as I open up a second VM, Network performance becomes extremely erratic on BOTH VM's and my downloads often fail. When I launch my first Windows VM, the Network performance on that VM is fine. On the NIC card dedicated to the Host, I've unchecked the "VirtualBox Bridged Networking Driver". On each of the dedicated VM NIC card, on the host machine, I've unchecked ALL Network options EXCEPT the "Virtual Bridged Networking Driver". All VM Network settings are configured with "Bridged Adapter" and each VM uses a dedicated NIC card. Each VM System's settings has the "Enable I/O APIC", "Enable PAE/NX", "Enable VT-x/AMD-V" and "Enable Nested Paging" settings Set. Clients OSes - Multiple Windows 7 圆4 Professional (issue shows up as soon as I have more than 1 VM, actually) VirtualBox 4.3.26 r98988 with the corresponding VBoxGuestAdditions on the guest machines All the BIOS settings for Virtualization have been set. This has been driving me insane and I just can't find the answer anywhere.Ĭomputer runs Intel Core i7 5960x (8 Cores), 32 GB of Ram and the main board is an ASRock X99m Killer. ![]()
