[libvirt-users] Failing %check section.
by Jan Olszak 07 Nov '13

Hi there! I'm building libvirt-1.1.4 with the fallowing configuration. I had to modify the spec file: 1. Comment out requirements: xhtml1, scrub, shadow-utils 2. Added defines: %define _without_selinux 1 %define _without_hal 1 %define _without_libnl 1 %define _without_macvtap 1 %define _without_storage_fs 1 %define _without_network 1 %define _without_sasl 1 %define _without_qemu 1 %define _without_storage_lvm 1 %define _without_storage_iscsi 1 %define _without_storage_disk 1 %define _without_storage_mpath 1 %define _without_nwfilter 1 %define _without_libssh2 1 %define _without_hyperv 1 %define _without_phyp 1 %define dist tizen And the %check section fails. I attach the logs. Thanks! Jan

[libvirt-users] virConnectListAllDomains support for PowerVM
by Camilo Aguilar 06 Nov '13

06 Nov '13

Hey guys, I'm so glad you added the new set of virConnectListAllDomains functions, it simplifies a lot our work!. I was only wondering why there is no support for PowerVM. Is it that it hasn't been developed or is there some technical hardship? Best, Camilo Aguilar

[libvirt-users] libvirt networking using VLAN Tag basics
by Dan Sa 05 Nov '13

05 Nov '13

topology : two guest connected to physical LAN (vlan 620 and vlan 621) on host : 1) creating bridge br0 2) creating bridge for guest 1 and guest 2 - to separate traffic 3) virtual network1 : I have default NAT 192.168.122.x DHCP feeding IP to eth1 4) virtual network2 : I want to use 192.168.0.0 for eth0 my question is what would be my virtual network2 looks like : following is default xml : <network> <name>default</name> <uuid>8778244b-1a0c-c15f-c348-26462a07a639</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0' /> <mac address='52:54:00:3E:19:B3'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> </dhcp> </ip> </network> in virtmanager I assign this default to NIC1 and gets IP in range 192.168.122.x I want to define another network and assign to NIC2 so I can get IP in range 192.168.0.x my guest are on interface em2.620, em2.621 etc thanks

[libvirt-users] Using resource pools (in vmware vcenter) with libvirt
by Ashutosh Bisht 05 Nov '13

05 Nov '13

Hi I am evaluating use of libvirt to manage a cluster of ESXi servers. We plan to use "resource pool" concept of vcenter/vmware to easily scale-up or scale-down the cluster of ESXi servers >From vmware doc "Resource pools are partitions of computing and memory resources from a single host or a cluster" Since VM can be designated to hosts, clusters or "resource pool".. assigning VM to resource pool allows a simple way to manage scale-up / scale-down operations. This is because one doesn't need to know identity of ESXi server (from cluster of servers) to assign/place a VM.. one can just refer to resource pool. >From reading the doc of libvirt, it seems that libvirt always requires identity of ESXi servers in all the (vcenter) API calls. Is my understanding correct? If so, does libvirt have a similar concept/notion so that VM life-cycle can be managed without knowing identity of underlying server? with regards Ashutosh

[libvirt-users] Using certtool to generate certificates for ESXi
by Shiva Bhanujan 04 Nov '13

04 Nov '13

Hello, I'm using certtool to generate the server certificates for ESXi - http://libvirt.org/remote.html#Remote_TLS_CA. I just copy the server certificate and key as /etc/vmware/ssl/rui.crt and /etc/vmware/ssl/rui.key. And then use virsh to connect from a CentOS 6.4 VM running on it - "virsh -c esx://<esx IP>. I get the following error - error: internal error curl_easy_perform() returned an error: Peer certificate cannot be authenticated with known CA certificates (60) : Peer certificate cannot be authenticated with known CA certificates error: failed to connect to the hypervisor is there something basic that I'm missing? Regards, Shiva

[libvirt-users] Fwd: Help regarding virsh domifstat
by Rohit Bhat 01 Nov '13

01 Nov '13

Hi, I need a small help. I am working on a project where i have to monitor network activity of a VM running on KVM. I am interested in how much data is going into the VM and how much data is coming out of the VM. I checked on the net and found out virsh domifstat is the way to go about it. 1. But looks like these stats also include bytes related to control traffic for the VM. Is there a way to exclude that? I just want the size of actual data transfers. 2. Is there a way by which i can report the data transfer of VM with the outside world (outside hypervisor) only while excluding data transfer with any other VM on the same host or with the host itself? Thanks, Rohit
