[libvirt-users] Calling 'virsh' from within a hook script - avoid deadlock?
by TSADOK, Shlomi (Shlomi) 07 Nov '13

07 Nov '13

I'm trying to create a hook that attaches several virtio-scsi disks to a starting vm, and it seems like the hook enters a deadlock while attempting to do so. Is there any workaround around this? Any better way, forking virsh execution somehow? Could anyone explain why this is creating a deadlock in the first place? Isn't libvirt multithreaded? Thanks for the help! Shlomi ### hook script: #!/bin/bash enum_scsi() { scsi_devices=`cd /dev;ls sd[^a]*` } gen_hba_xml() { cat > ./hba.xml << EOF <controller type='scsi' model='virtio-scsi'/> EOF } passthrough_start() { # create virtio-scsi HBA gen_hba_xml virsh attach-device --persistent $domain_name ./hba.xml rm -f ./hba.xml # attache scsi devices to guest enum_scsi for sd in ${scsi_devices[@]} do virsh attach-disk --persistent $domain_name /dev/${sd} ${sd} done } domain_name=$1 domain_event=$2 case $domain_event in start) passthrough_start ;; *) echo "qemu hook called with unexpected options $*" >&2 ;; esac ### starce libvirt: [root@localhost ~]# strace -f -p 14630 Process 14630 attached with 11 threads - interrupt to quit [pid 14640] futex(0xc34ebc, FUTEX_WAIT_PRIVATE, 2303, NULL <unfinished ...> [pid 14638] futex(0xc34ebc, FUTEX_WAIT_PRIVATE, 2303, NULL <unfinished ...> [pid 14637] futex(0xc34ebc, FUTEX_WAIT_PRIVATE, 2303, NULL <unfinished ...> [pid 14636] futex(0xc34ebc, FUTEX_WAIT_PRIVATE, 2303, NULL <unfinished ...> [pid 14635] futex(0x7fcc240ccd80, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...> [pid 14639] futex(0xc34ebc, FUTEX_WAIT_PRIVATE, 2303, NULL <unfinished ...> [pid 14634] futex(0x7fcc240ccd80, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...> [pid 14631] restart_syscall(<... resuming interrupted call ...> <unfinished ...> [pid 14633] futex(0x7fcc240ccd80, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...> [pid 14630] restart_syscall(<... resuming interrupted call ...> <unfinished ...> [pid 14632] futex(0xc34e24, FUTEX_WAIT_PRIVATE, 3091, NULL^C <unfinished ...> ...

[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] 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

[libvirt-users] upstart script for virtlockd

Hi all, Trying to test libvirt 1.1.3 with virtlockd locking my qcow2 images on a NFS storage between two kvm hosts. ./configure ... --with-init-script=upstart Libvirtd upstart script is actually well generated but I can't see nothing about virtlockd... or am I blind ? :) Nevertheless, running virtlockd -d && service libvirtd restart works fine. Am I wrong thinking that editing qemu-lockd.conf with my needs and qemu.conf with lock_manager="lockd" was enough ? Thank you for your help.

[libvirt-users] libvirt_lxc: SELinux MCS
by Matteo Piccinini 31 Oct '13

31 Oct '13

Hello list, my name is Matteo, i'm new on that list. I'm working on a multitenancy platform with linux containers through libvirt on a production system with Red Hat 6.4. Every container run a separate instance of OpenSSH and Apache HTTPd and I need to give root privileges to the developers and I try to configure SELinux using svirt and MCS. I try the secmodel type dynamic and static in the xml file but it didn't work, I received the following error: error : virSecurityLabelDefParseXML:3228 : XML error: security label is missing error : virNetSocketNewConnectUNIX:566 : Failed to connect socket to '/var/run/libvirt/lxc/cntr1.sock': Connection refused I configure the followings secmodel definition and used chcon on the rootfs directory (created with yum) with "system_u:object_r:svirt_lxc_file_t:s0:c30,c50" label: <seclabel type='static' model='selinux' relabel='no'> <label>system_u:system_r:svirt_lxc_net_t:s0:c30,c50</label> </seclabel> or: <seclabel type='dynamic' model='selinux' relabel='yes'> <label>system_u:system_r:svirt_lxc_net_t:s0:c30,c50</label> </seclabel> I try to compile the last version from the master branch of git the result was always the same, the error was related to the SELinux driver not enabled. The output from "virsh -c lxc:/// capabilities" doesn't show the secmodel and doi tag like the qemu/kvm have for the lxc driver the selinux driver. How can I enable the SELinux driver for libvirt lxc in Red Hat 6.4? SELinux is in enforcing mode. Thanks in advance, Matteo

[libvirt-users] A RFE for libvirt
by shyu 30 Oct '13

30 Oct '13

Hi libvirt guys, I am an newbie to libvirt. There is an requirement for libvirt: Every time I want to rename an guest by virsh command, I need to virsh edit origin_guest(edit the name,delete/edit the uuid) after that a new guest with the same configuration as origin_guest was defined, then virsh undefine origin_guest. Seems it's a little complex, so should be there an virsh command like "virsh rename origin_guest new_guest"? I know I can use virt-manager to rename an guest,but if there is an virsh command can do it, I think it's much useful. Thanks -- Regards shyu

[libvirt-users] Automatically assign static ipv4 via dhcp to new VMs
by Tim 30 Oct '13

30 Oct '13

Hi guys, I'm running a KVM/libvirt host in a datacenter and got a fancy IPv4 subnet from my provider. I'm able to assign IPs from that subnet via dhcp to my VMs: host01 ~ # virsh net-dumpxml internet <network connections='3'> <name>internet</name> <uuid>37b888cc-510f-46f1-9246-346da96222ed</uuid> <forward dev='enp5s0f0' mode='route'> <interface dev='enp5s0f0'/> </forward> <bridge name='virbr1' stp='on' delay='0'/> <mac address='52:54:00:13:39:d5'/> <ip address='XX.YY.253.2' netmask='255.255.255.224'> <dhcp> <range start='XX.YY.253.4' end='XX.YY.253.30'/> <bootp file='pxelinux.0' server='XX.YY.99.100'/> </dhcp> </ip> </network> What I would like to do: 1) Right know it seems like dnsmasq assigns ip-addresses randomly to VMs, is there any way to assign them in ascending order? 2) IPs are not statically assigned. Is it possible to add something like this automatically at the first VM-start to the xml definition?: <host mac='AA:BB:CC:DD:EE:FF' ip='192.168.122.2' name='foobar'/>
