[libvirt-users] failed to initialize directx in w7
by arnaud gaboury 21 Aug '14

21 Aug '14

I am not sure this issue is tight to Red Hat qxl GPU driver, but I can't initialize directxX on a guest windows 7. Trying to start a game, I get the error message : Failed to initialize directX Of course, directX is installed on the w7 guest, and properly. The dxdiag command, a directx diagnostic tool, does not show any error. Some summary under the video : Driver name : Red Hat QXL GPU Processor type : SeaBIOS VBEC(C) 2011 No Directx functionality are available (Direct Draw, Direct3D, AGP texture) I am not a windows expert, but I would like to know if DirectX is compatible with QXL driver. If not, what is the process to be able to run directX on the windows guest ? If both are compatible, what did I miss ? The VM is working perfectly with virtio & qxl. Please find below my virt-install command: ----------------------------- virt-install --connect qemu:///system --name=tintinWinoz --memory 4096 --cpu host-model-only --os-variant=win7 --disk /myVM/tintin --boot cdrom,hd --virt-type kvm --graphics spice --controller scsi,model=virtio-scsi --cdrom /dev/cdrom --disk /drawer/myIso/w7.iso,device= cdrom ----------------------------------------------------- I thereafter installed manually from the w7 guest virtio & qxl drivers. Thank you for advises.

[libvirt-users] Libvirt Java API to get CPU usage of VM (KVM)
by Restituto Marcus Arevalo 20 Aug '14

20 Aug '14

Hi all libvirt-users, Is there a counterpart on Java of the function virDomainGetCPUStats that is based on C API? Because I am trying to create a program based on java to get the CPU usage of a Guest/Domain/VM in KVM using the Libvirt Java API. Honestly, I am having a hard time in starting my program. I have no idea where to start. I mean, what functions do I need to get the CPU usage of the guest/domain in KVM? I know there are other options but I am avoiding in connecting to the VM through SSH and get the CPU usage. To make things easier to understand, I need to know how the Virtual Machine Manager in Linux is able to output a graph of the CPU usage of EACH VM. I really need help. I have no idea where to start. Any suggestions would be much appreciated. I'll try to post a screenshot of the graph later. regards, Marco

[libvirt-users] virt-install: failed to initialize KVM: Permission denied
by arnaud gaboury 20 Aug '14

20 Aug '14

As a regular user, member of the libvirt group, I run this command to create a basic VM: virt-install --connect qemu:///system --name=test --ram 2048 --cpu host-model-only --os-variant=win7 --disk /myVM/test --boot cdrom,hd --virt-type kvm --graphics spice --controller scsi,model=virtio-scsi --cdrom=/drawer/myIso/w8.iso It returns an error : --------------------------------- Starting install... ERROR internal error: process exited while connecting to monitor: Could not access KVM kernel module: Permission denied failed to initialize KVM: Permission denied --------------------------------- $ getfacl /dev/kvm # file: dev/kvm # owner: root # group: kvm user::rw- user:martinus:rw- group::rw- mask::rw- other::--- The command return seems to indicate rights are correct. $ lsmod return kvm & kvm_intel are loaded. If I run the virt-install with qemu:///session, I do not have this issue and can create the VM. I found many entries about the KVM permission issue, but with no clear answer to solve it. Thank you for any suggestion -- google.com/+arnaudgabourygabx

[libvirt-users] Guest vlan trunk port networking issues
by Dennis Jacobfeuerborn 20 Aug '14

20 Aug '14

Hi, I'm having trouble getting networking to work and I'm not sure what I'm doing wrong. The network interface of the host is connected to a switch-port that is configured as trunk and allows tagged traffic for vlan id 10. The host itself has the interfaces eth1.10 and eth1 defined. eth1.10 is configured with the primary ip address of the host system and eth1 is slave of the bridge br1. I installed a guest with a virtual network interface that is added to br1 the idea being that I can define an interface eth0.10 in the guest and have the tagged traffic forwarded this way: (guest) eth0.10 (packet gets tagged with id 10) -> (host) vnet0 -> (host) br1 -> (host) eth1 -> network The issue is that when I do a ping in the guest I see the arp request on eth1 with tcpdump but no response as if the packet doesn't reach its target. Normaly at this poing I would suspect the switchport configuration but when I ping the same IP from the host (which has an IP in the same network on interface eth1.10) this ping works fine. Does anybody have experience with this and maybe an idea why the host can reach the ip in vlan 10 but the guest can not? Could this be a routing issue that the system somehow discards the packets flowing through eth1 directly because there also is an interface eth1.10 present? Regards, Dennis

[libvirt-users] How to install libvirt-python from source code?
by Can Zhang 19 Aug '14

19 Aug '14

Hi, I’d like to install a latest version libvirt on CentOS 6.5. I compiled libvirt, it worked well and then I tried to install libvirt-python. The version is libvirt-python-1.2.7, and I used `python setup.py build` and `sudo python setup.py install` to install. But in python, I get errors like: ========== >>> import libvirt Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.6/site-packages/libvirt.py", line 28, in <module> raise lib_e ImportError: /usr/lib64/python2.6/site-packages/libvirtmod.so: undefined symbol: virTypedParamsAddBoolean ========== Someone would help? Best regards, Can Zhang

[libvirt-users] Libvirt-install w8 iso
by arnaud gaboury 16 Aug '14

16 Aug '14

I am using this command to install a w8 guest on my Archlinux host: virt-install --connect qemu:///system --name=tintinVM --ram 4096 --cpu host-model-only --os-variant=win7 --disk /dev/vg0/tintin,size=120,bus=virtio,sparse=false,format=raw --name="tintinVM" --network bridge=virbr0,model=virtio --graphics spice --cdrom /dev/cdrom The virtual machine window open and show the blue windows logo. But then nothing happens and I can't start the install process. I hav eno idea why. The w8 iso file is clean. I test booting from it and I can start the install. What is wrong with my command? How can I try another way (like mounting the ISO on a dir). I dual boot arch and w8, so there is already a w8 installed on my ssd. Maybe can make an .img of the installed w8 then use this img ? Or directly use the partiton? I must add my machine boots in EUFI, not sure it has something to do. Then, I have issue when loading KVM kernel modules: permission denied. The user is in the KVM & qemu group, and /dev/kvm belongs to user:kvm. I need to # rmmod kvm_intel before I start $ virt-install ..... Last, I don't understand well if I need to use qemu///system or qemu///session ? My goal is to let users start a VM when in their arch session. Thank you for any suggesuions. -- google.com/+arnaudgabourygabx

[libvirt-users] virt-manager and libvirt-python
by Фарит Мутугуллин 15 Aug '14

Hello! I'm trying to work with virt-manager but getting SIGTRAP signal. It is done with gdb under MinGW32 on Windows 7 64-bit. I have Python 2.7.8. 32-bit. As I can see from backtrace ( http://pastebin.com/JhN6XgYb ), there is something wrong with libvirtmod.pyd. Also I couldn't find how to solve " typelib for AppIndicator3" error. So I try to debug libvirt-python. For doing this, I building libvirt-python with -g flag. python setup.py build --compiler=mingw32 -g install But I have undefined reference to _imp__Py_InitModule4. http://pastebin.com/9gw1zsmw Earlier I built Python with debug info as -lpython27_d was needed. I tried to build with python_d, but got the same error. Nevertheless, when I build without -g, everything builds just fine. Could you tell me what am I doing wrong? Or is SIGTRAP coming from somewhere else? What SIGTRAP can be caused by?

[libvirt-users] Ubuntu 14.04 LTS KVM issue: setdev ioctl failed on blockpoll: Device or resource busy
by Jianfeng Tang 14 Aug '14

14 Aug '14

> Hi, I ran into a strange issue when I brought up my virtual device on KVM after I upgraded my box to Ubuntu 14.04 LTS. My virtual device has two disks: one boot disk and one empty disk. It was able to boot up, but ioctl on the second disk image failed with error messages like: setdev ioctl failed on blockpoll: Device or resource busy Any thoughts what happened. It worked fine with Ubuntu 12. Our virtual device called open_bdev_exclusive and failed. AppArmor seems not the problem because I saw the same issue with app armor disabled. Thanks. >
