What is the correct combination of packages to configure and manage VMs via virt-manager undet CentOS-5.4? If I use qemu then while virt-manager works I obtain SELinux alerts with respect to the real-time clock. If instead of qemu I use kvm-qemu-img then virt-manager simply does not work. It starts but it does not find any form of qemu and the selection boxes are all greyed out. Further, do I

I am experimenting with a kvm virtual machine. At the moment I trying to configure iptables for the the host instance. In Xen terms I would call this Dom0 but I do not know the appropriate KVM term, if any. The setup I have is a single NIC (eth0) host bridged (bridge0). I want iptables to allow all host generated traffic (! bridge0 I think) and to check all other traffic for brute force

I am in the middle of a rather confusing situation. At the moment I am unable to shutdown a KVM guest machine. Nor am I presently able to open a virt-manager session on the host. I am not exactly sure what has happened but the problem with the vm guest is that issuing a "virsh shutdown 1" from the root console has no effect. # virsh list Id Name State

We use a dual homed CentOS-6.3 host for our Internet gateway router. Its internal nic (eth1) is configured such that the address 192.168.0.1 is one of its aliases. # cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0

CentOS-6.0 I created an lv (120 Gb) to hold the image of a KVM guest instance. I mounted this at /var/lib/libvirt/images/lv_guest01. When I do a df I see the lv is mounted at the desired location. When I run the virtual machine manager from the desktop I am given the option to install the image into the root directory tree or to browse for an alternative location. When I browse to the mount

I have a kvm guest running MS-WinV7 on a CentOS-6.5 host. The WinV7 guest was installed from a CD. It installed correctly and was updated and added to an MS Active Domain without difficulty. I was able to do work on it through the virt-manager console and I was able to shut the system down from the console without problem. I cannot get it to restart however. virsh start

Is it possible to use this exploit against a kvm guest to read memory used by the host? In other words: if an exploitable service, say httpd with mod_ssl, is running in guest system 'vm1' hosted on system 'virthost' then what implications does that have with respect to guests vm2 and vm3 and to virthost itself? -- *** E-Mail is NOT a SECURE channel *** James

I have a KVM vm running CentOS-6.8 on a host also running CentOS-6.8. This instance is used for occasional development projects which require segregation. Thus it is seldom accessed. At some point in the recent past this guest developed an issue with starting. Specifically these messages were found in the system log files: /var/log/messages-20170312:Mar 10 16:31:06 vhost04 kernel: dracut:

I am contemplating converting some of our internal networks from routable to private IPv4 address space. I have a question about RIP as implemented under Cisco IOS 12.x. Presently the setting for rip is: router rip version 2 passive-interface [[FastEthernet]]0/0 network aaa.bbb.ccc.0 no auto-summary What I would like to know is how one routes the entire 192.168/16 address space using rip.

Need to start a virtual machine but missing nic is preventing this: I have need to recover some data from a guest on host which has been shutddown for some time. The host had one of it nic removed at some point. It is not likely to be replaced either. When I try to start the guest in question I get this: error: Failed to start domain inet09.harte-lyne.ca error: Cannot get interface MTU on

i86_64 CentOS-6.5 I have installed a Windows instance as a kvm guest on a host running CentOS-6.5. I can access the desktop through the virt-manager console and everythign seems to work, although the mouse cursor seems to get lost from time to time. The virt-manager console display supports various resolutions but when I re-size the desktop display remains essentially a square inside a letter

We are trying to move our mail store from a host running cyrus-imapd 2.2.12 under CentOS-4 to one running 2.3.16 under CentOS-6. The current host is a 32 bit architecture. The new host is 64 bit. We have followed the update guide found at: http://www.cyrusimap.org/docs/cyrus-imapd/2.3.16/install-upgrade.php The steps we followed were: 1. Install cyrus-imapd et al on the new host. 2. Modify

I installed a new CentOS-6.3 kvm guest on a recently provisioned kvm host also running CentOS-6.3. This guest will not connect to the network and the host cannot connect to it via its public IP address. I had previously installed a guest system on thst same kvm host using the same ISO and that system connects to the network without problem. I next created a third guest isntance and this too does
