Re: [VBox-users] key combinations in CLI
From: John A. Wallace [mailto:jw72...@verizon.net] The instruction says that I can use a keyboard combination of Alt+Ctrl+F1, In Virtualbox, go to File / Preferences / Input. See what your Host key is. If your host key is Ctrl and you're trying to send Ctrl-Alt-F1 to the guest, then as soon as you hit Ctrl, guess what happens. You're sending Ctrl-Alt-F1 to your host, not the guest. Notice, in VirtualBox, what they call Ctrl and Alt are actually Left Ctrl and Left Alt. They make a distinction between Right Ctrl and Right Alt, but I don't know why they're not more explicit in naming the left key Left. So if you don't want to change your Host key, you might consider using the Right Ctrl, Right Alt, F1 to send your signal to the guest. -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

[VBox-users] Poor networking performance
I have a Linux (Ubuntu Precise 64) host with both Windows and Linux guests. I've been noticing some poor network performance from the Linux guests - I just did a quick test. The guests are configured with bridged networking, using the paravirtualized network adapter. Guest additions are running. Pinging the host adapater on the host is an average 0.066 ms Pinging a Windows guest from the host is an average 0.380 ms Pinging a Linux guest from the host is an average 7.526 ms I get the same results from two different Linux guests, one 32-bit and one 64-bit. The 32-bit is a fresh install, so unless something is broken in the Ubuntu Precise defaults I didn't do it. Why am I getting such poor networking performance from the Linux guests? -- Daniel -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

After some googling, I tried changing the Linux guest network adapter to the Intel Pro 1000/T Server. Now network performance is up where it should be. I also saw the Windows guests had been using the Intel as well. Why is the virtio so slow - I thought that was the optimized one?! -- Daniel -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

This doesn't fit the profile exactly, but it may have something to do with the tcp offloading issues. What happens if you ping an ip address not on the host from the linux guest? Like a remote gateway or something. Geoff -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
