[libvirt-users] can't up the eth in the vm and access to network
by guan qin 04 May '11

Hi, I encounter a problem that the eth can't be up in the VM by using VT-d. I boot the VM using "virsh create vt_d.xml". The VM could recongize the NIC which was assigned .then I do in VM as follows: #cat /sys/class/net/eth0/operstate down #ifconfig eth0 up #cat /sys/class/net/eth0/operstate down #ficonfig eth 10.100.0.5 #cat /sys/class/net/eth0/operstate down more system information is attached.(uname 、ifconfig 、lspci、cmdline...) I can't figure out the reason why the eth is still down? can anyone help me ? best regards, qinguan vt_d.xml: <domain type='kvm'> <name>test</name> <description>just test using sriov!</description> <os> <type>hvm</type> <boot dev='hd'/> </os> <memory>524288</memory> <currentMemory>524288</currentMemory> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <features><pae/><acpi/><apic/></features> <clock offset='utc'/> <devices> <input type='mouse' bus='usb'/> <disk type='file' device='disk'> <source file='/home/qinguan/exp/ubuntu_1.img'/> <target dev='hda' bus='virtio'/> </disk> <emulator>/usr/bin/kvm</emulator> <graphics type='vnc' port='-1'/> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address bus='0x0' slot='0x19' function='0x0'/> </source> </hostdev> </devices> </domain>

[libvirt-users] LibVirtD Networking
by ssaleh＠nrln.us 03 May '11

03 May '11

I'm looking for the best way to setup networking support for VM's. I have a small subnet with 6 routable IP's I can use on the Internet. So, I'd like to setup a host and have VM's on the public IP's. The computer I have has 4 NICs. I'd like to use one for a private 10.x.x.x and the others for the public facing VM's. Can I support 5 VM's with the three raminging NIC's? Should I use virtual IP's for the 5 VM's? Should I use a single NIC for all 5 VM's (similar to what VMWare does)? What is the best way to newtork this solution? Thanks in advance.

[libvirt-users] [Libvir] libvirt & vde_switch
by Robert Šmol 02 May '11

02 May '11

Hi, I would like to ask about status of VDE and libvirt. I found a thread from http://www.redhat.com/archives/libvir-list/2008-February/msg00030.html. I am not interested in connecting the VDE to the outside world. I have created a FW machine using macvtap. To this machine I would like to attach machines from different zones (dmz, prod, cust). I was thinking on using VDE and vlans (FW would have 1 interface in each vlan - machines also), but I am not aware how to configure this in libvirt. I now assume I can do the same setup with regular bridges for the moment (benefit of VDE would be only 1 switch for many vlans).

[libvirt-users] port forwarding
by Ireneusz Szcześniak 28 Apr '11

28 Apr '11

Hi, I'm using CentOS release 5.6 (Final) and Xen 3.1. I'm writing to ask how to configure port forwarding. With virt-manager 0.6.1 I added the machines, but there I don't see an option for port forwarding. I would like to reach the VM on a specific port of the host machine. Once the machinces are running, I can configure iptables so that the port forwarding works, but after host reboots, other rules are inserted (put in front of my rules), which disable my rules. I guess these rules are put by libvirt, and so I'm writing to this list. These are the rules inserted: Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable I need to have a different rules for 192.168.122.0/24: the states RELATED,ESTABLISHED are fine, but I need the NEW state put there too, so that the new forwards can go through. Thanks, Irek -- Ireneusz (Irek) Szczesniak http://www.irkos.org

[libvirt-users] Disk not bootable from yesterday resolved
by David Brown 27 Apr '11

27 Apr '11

Just an update and a thanks. The not bootable issue I was having yesterday ended up being for some odd reason the disk type in the domain define xml file had been switched to the disk being "raw" rather than qcow2 format. When I changed:<driver name='qemu' type='raw'/> to <driver name='qemu' type='qcow2'/> It booted without issue. I'm not clear how that got changed on the original domain. It was in use without issue about a week ago. :/ I then ran the clone again and it cloned fine, but had the boot issueagain. I checked the cloned domain.xml file and again it said typeraw. I changed it again to qcow2 and it booted fine. Bug? Shouldn't it keep the type in the config the same? Anyway, thanks for help and especially the quick responses! Dave

[libvirt-users] problem installing libvirt from source
by Lars Nordin 27 Apr '11

27 Apr '11

I'm trying to compile and install libvirt-0.9.0 on Ubuntu v10.04. The make and install went fine and I don't see any errors but there isn't a libvirt directory created in /usr/local/lib/python2.6/dist-packages. I specified configure --with-vmware -with-esx (and later --with-python), then make, then sudo make install. >From config.log: prefix = /usr/local exec_prefix = ${prefix} pyexecdir = ${exec_prefix}/lib/python2.6/dist-packages pythondir = ${prefix}/lib/python2.6/dist-packages pkgpyexecdir = ${pyexecdir}/libvirt pkgpythondir = ${pythondir}/libvirt

It says: booting from hard disk Booting failed device not bootable FATAL: failed to boot from device. Or something very similar.

[libvirt-users] virt-image issue
by Zvi Dubitzky 27 Apr '11

27 Apr '11

Hi Does anybody work with the virt-image utility. - I do not see where/how one specifies the pre-defned image or the CD iso image to produce the image from - what is the .xml file requested for ? I guess it is the output xml file I just used the command with an existing .xml file (thought the utility will modify it according to the specified flags) but got the error message : "ERROR Cannot parse 'vmTest3.xml': Root element is not 'image" Any idea what is missing ? thanks Zvi Dubitzky Email:dubi@il.ibm.com

Hi, Not sure if this is the right mailing list, but... I have a Linux VM (CentOS 5.4) VM. I cloned it with virt-clone, but the clone isn't bootable. When I attempt to boot it says: Booting from hard diskBoot failed: not a bootable diskFATAL: No bootable device The clone was made with the following command: virt-clone -o centos -n centosclone -f /path/to/new/image.img I've attempted it several times and get the same result. Has anyone seen this or know how to resolve it? Thanks,Dave

[libvirt-users] Adding more disks...
by Dale Amon 26 Apr '11

26 Apr '11

I need a VM with about 6-8 qcow2 disk images, but it seems to only allow 4 disks on the ide, like the real hardware. What lines do you need to add on to the xml definition file to get hde, hdf, hdg, etc?
