similar to: running kvm and vnc same time

Ran into something weird. I have my machine CentOS 6.2 running KVM guest of Windows 7. This works fine while I'm in the office... Then when I remote in using VNC to my machine - the VNC always works fine. However, when I try to access the KVM session its like the mouse has lost its brain. Anyone ran into this? I startup with this command: qemu-system-x86_64 -net nic,model=rtl8139 -net user

All - I am running a virtual windows 7 (pro 64) on centos 5.5 x86_64. I was hoping to run virtual XP inside windows7 in this configuration. I get an error about cannot start virtual XP when I try this. Do I not have something setup correctly or can I not run a "double" virtual environment? Thanks, Jerry

A patch that was applied yesterday tried to turn the vnc option off if dryrun was set. Unfortunately, the way it was actually coded turned vnc ON if dryrun was not set! I think this patch should fix it (someone who actually uses vnc & dryrun should test it, though). -George +-------------------+---------------------------------------- | dunlapg@umich.edu |

Hi all, I've started playing with kvm on CentOS 5.5, with not much success so far. In a nutshell, I have the same problem as http://lists.centos.org/pipermail/centos-virt/2010-April/001854.html I followed the RHEL5 virtualization guide to set up a bridge interface br0, and then used virt-install (rather than virt-manager - I like automation) to set up the vm. It hangs at some point.

Any one using vnc server on centos 5.1? on 4.6 I had no issue. on 5.1 I am having times when on connetion the VNC serveris crashing and logs me out of all my open'ed items. I can relog in. But I was wondering if others are seeing this and if there is something to do about it. THanks, Jerry

Can somebody point me to a HowTO or other documentation describing the tools available under the CentOS 5 KVM package to create and manage a Windows 7 Pro VM? All my VM experience to date has been the old free VMware Server. I need to: + Create the VM instance allowing for about 50GB total disk space which will be either a single image partitioned into two Windows 'Drives'

I finally got access to some machines with more resources than the free VMware ESXi license allows which pushed me into trying kvm instead. Seems capable enough for what I need and can even import and run the existing vmdk images I already have. But, I have some questions about accessing the virt-manager console remotely for initial configuration, etc.. Normally I use freenx for remote GUI

I am trying to get a remote screen on C7. I did the following on C7 server: yum install tigervnc-server cp /lib/systemd/system/vncserver at .service /etc/systemd/system/vncserver@:1.service systemctl daemon-reload edit /etc/systemd/system/vncserver@:1.service and replace <USER> with myuser su - myuser run

I have a bunch of VBox Linux VMs (CentOS 6/7, Debian7/8/9, Ubuntu (14.0/16.04, Alpine) that get dynamic IPs. To get their respecitive IP addresses I have to login and run 'ip addr' I would like such info to be displayed on the VM console *before* the login prompt. Ideally an ASCII log + info (see below sig line). Thus, I can get the info from the VM console without having to login. I

A client is insisting to install CentOS 6.2 32 bit version [1] on a system with 4GB RAM. Lately, I have done 64 bit installations only; not sure if the 32 bit kernel supports pae for >= 4GB RAM. If anyone knows the answer please let me know (will save me time on an installation in my setup). [1] The Client's ERP vendor has validated the application on the 32 bit platform only thus the

Hi all, I would like to install/test CentOS 7.X as a hostap for my home. I am thinking to use an Alfa (http://www.alfa.com.tw) usb wireless adapter or TP-Link. BUt there is not much information in Alfa's or TP-Link's web sites about which of them can run as a HostAP. If I can find any adapter that supports ac with a throughput of 150 Mbps/300Mbps, it would be great. Any recommendation?

I have setup a Zentyal 3.2 Samba4 AD. I am using RSAT to administer the AD server. Windows7 and Linux (CentOS) clients are able to join the AD; uid/gid of directories/files show up as per the definitions in Samba4. With Mac OS X clients, there is a problem. The OS X nodes are able to join the domain (quite a few blogs on this subject). The AD connection shows green button. The AD user is
