I believe my Centos 7 DVD did not have any options for graphical images, so it should just install a minimal, non-graphical image. Use virt-manager to install Centos 7 in the standard fashion - I will leave out the details. Here is the standard way to do a graphical VM, using virt-manager, with a guest image that is not too large.

Burtįollowup to my "how to use virt-manager" and how to get a small VM study. Other conclusion: too bad that CentOS has the slow gcc-4. Conclusion is that usually VirtualBox is the way to go. I haven't tested this in terms of removing packages and dependencies, etc.

(I got stuck with 32bit Windows Vista taking up most of the tiny disk, so I had little space to work with.) It is possible that by using the somewhat nonstandard method in my first note, you can eliminate the guest Xserver, and that may be about 500 MB. My original goal was to conserve disk space. I have a strong feeling that this won't work easily unless you are lucky and the preceding problem (b) has not happened to you. I am told that you should be able to copy/paste between guest and host. But there are constant bugs being fixed and you either get lucky or you become a super expert on many things.

The professional thing would be to issue "systemctl start gdm" rather than directly starting gnome-shell. If you shrink the host window that has the guest X, fonts will shrink. You should get a new window on the host that has the Xserver for the guest and an xterm there. start the guest OS if not already done so, log in, and then issue xinit at the guest login d. start spicy or virt-viewer or virt-manager's viewer c. Now it appears I can get good graphics via 2 methods: 1. Just a follow up for anybody interested in using qemu-kvm-spice like I mentioned. I start Ubuntu Server and it comes up in text mode. My soon to be friend John Stanford White would walk around the lab every day and he would see a bunch of people with Sun Windows on their screens, except for one guy who had just one large text display covering the entire CRT. I had never used a graphics terminal before. I was working in a lab where about 20 people were seated at tables with Sun monitors. At the moment I have the olvwm window manager, which I understand is similar to the first time I used X on a Sun Workstation. Note that I started off with a non-graphical Ubuntu Server, and then tried adding just enough to get graphics. Here is a procedure that works nicely, but requires some security reductions, while bringing the X-Windows behavior back to what we remember from the 1990s. So if you shrink a virt-viewer window, the text font shrinks rather than what we are used to when resizing a terminal window. This is largely related to resizing windows. I ran into issues with the guest graphics being blurry, and my glasses aren't perfect, and my eyes aren't perfect, but there was no doubt that the graphics really sucked. Now I am looking for advice about VM graphics, and I put the question out here, since some folks are likely using VMs. Gcc 4.8.5 Thu Mar 16 10:14: start Thu Mar 16 10:47: stop gcc 5.4.1 Thu Mar 16 10:59: start Thu Mar 16 11:17: stop I will give the VM speed worry a rest. Here are the results of "make build-release": I ignored gcc 6 this time, but I compared gcc 4.8.5 to gcc 5.4.1. So I re-ran my tests just using the host. CentOS has gcc 4.8, and Ubuntu has gcc 6. My VM is CentOS 7, and my host is Ubuntu Server 16.10. It finally dawned on me that I had not controlled the version of gcc used. After hours of building VPP with all sorts of tweaks in # of processors assigned to the VM, memory assigned, and even the -j argument to make controlled in build-root/Makefile, I was having no luck.

The processor is Core 2 Duo, and therefore it has all the Intel VT-x virtualization hardware needed for KVM which I am using (it also has all the interesting extensions like SSSE3 for DPDK, even though it is older than my AMD processor.) I read that the VM should execute code almost as fast as native. I was tearing my hair out when I found that my VM build of VPP was taking much longer than a build on the base machine. The original goal was to set something up in limited space on a Lenovo T400 laptop. I have been trying to get a pleasant VM environment on a laptop.
