[libvirt] VMware ESX: Allow leading dots in VMX config entry names
by Matthias Bolte 27 Jul '09

27 Jul '09

Hi, '.encoding = "UTF-8"' is a valid VMX config entry, so the virConfParser must accept it in VMX mode. This patch lets the parser accept those names with leading dots. Regards, Matthias

[libvirt] Unable to get libvirt working with KVM using direct kernel boot.
by Tiit Kaeeli 27 Jul '09

27 Jul '09

Hi, I am trying to get libvirt to manage a KVM virtual machine on Debian squeeze with multiple relevant parts included form unstable (because of need for gpt partition tables, Intel 82576 nic etc). Unfortunately the VM does not seem to boot. I will see a quemu prompt on /dev/pts/1. (Tried pressing c on it, but no difference). Nothing will appear on /dev/pts/2, /dev/pts/3 or when I type virsh console vm1_storage. If I grab the kvm command line generated by libvirt using ps and run it manually, it works fine. (Starts booting after I press c on /dev/pts/1 or remove the -S option from the command line) Libvirt configuration file: <domain type='kvm'> <name>vm1_storage</name> <uuid>29bfac01-b24d-e4ab-e741-f33f7e880d9d</uuid> <memory>4096000</memory> <currentMemory>4096000</currentMemory> <vcpu>6</vcpu> <os> <type>hvm</type> <kernel>/boot/vmlinuz-2.6.30-1-amd64</kernel> <initrd>/boot/initrd.img-2.6.30-1-amd64</initrd> <cmdline>"root=UUID=98d6d3d7-3782-4f6b-a94f-bc0272c0289d ro console=tty0 console=ttyS0,115200n8"</cmdline> </os> <features> <acpi/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='block' device='disk'> <source dev='/dev/vm_lvm/vm01_storage_root'/> <target dev='vda' bus='virtio'/> </disk> <interface type='ethernet'> <mac address='52:54:00:12:34:56'/> <target dev='tap0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> </devices> </domain> KVM command line that I see in ps after running virsh define /etc/libvirt/qemu/vm1_storage.xml virsh start vm1_storage (Works fine after I remove the -S option or press 'c' on quemu monitor on /dev/pts/1): /usr/bin/kvm -S -M pc -m 4000 -smp 6 -name vm1_storage -uuid 29bfac01-b24d-e4ab-e741-f33f7e880d9d -nographic -monitor pty -boot c -kernel /boot/vmlinuz-2.6.30-1-amd64 -initrd /boot/initrd.img-2.6.30-1-amd64 -append "root=UUID=98d6d3d7-3782-4f6b-a94f-bc0272c0289d ro console=tty0 console=ttyS0,115200n8" -drive file=/dev/vm_lvm/vm01_storage_root,if=virtio,index=0,boot=on -net nic,macaddr=52:54:00:12:34:56,vlan=0 -net tap,ifname=tap0,vlan=0 -serial pty -parallel none -usb /var/log/libvirt/qemu/vm1_storage.log shows: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin HOME=/ /usr/bin/kvm -S -M pc -m 4000 -smp 6 -name vm1_storage -uuid 29bfac01-b24d-e4ab-e741-f33f7e880d9d -nographic -monitor pty -boot c -kernel /boot/vmlinuz-2.6.30-1-amd64 -initrd /boot/initrd.img-2.6.30-1-amd64 -append "root=UUID=98d6d3d7-3782-4f6b-a94f-bc0272c0289d ro console=tty0 console=ttyS0,115200n8" -drive file=/dev/vm_lvm/vm01_storage_root,if=virtio,index=0,boot=on -net nic,macaddr=52:54:00:12:34:56,vlan=0 -net tap,ifname=tap0,vlan=0 -serial pty -parallel none -usb char device redirected to /dev/pts/1 char device redirected to /dev/pts/2 qemu: loading initrd (0x76055b bytes) at 0x000000007f89f000 Versions in use: kvm 85+dfsg-4 libvirt0 0.6.5-2 libvirt-bin 0.6.5-2 linux-image-2.6.30-1-amd64 Thanks for any ideas.

I'll try with 7.15 can I test with ESX4i?

No, but installing in the /usr/local prefix should also work with pkg-config. The .pc for libcurl should be located at /usr/local/lib/pkgconfig/libcurl.pc and pkg-config should find it. Maybe you have to set PKG_CONFIG_PATH in order to have pkg-config pick it up. Check the output of: pkg-config libcurl --modversion It should output 7.18 or what ever your version is, if installed correctly. > btw - Do I really need libcurl 7.18? trying to install it pushing me into > the depnendncy hell: [...] Hm... I just looked at the changelist of libcurl and something older like version 7.15 may also work, but I haven't tested it. You could give it a try and edit the configure.in file and change 7.18 to 7.15 and see if that works out. Regards, Matthias

[libvirt] VMware support and libcurl on rhel-u1
by Shahar Klein 26 Jul '09

26 Jul '09

I'm trying to play with the new ESX driver on a rhel5-u1 x86_64 but I get this: checking for libcurl libraries >= 7.18.0... configure: error: libcurl >= 7.18.0 is required for the ESX driver according to http://curl.haxx.se/download.html there is no rpm for rhel x86_64 so I built it and tried: export LIBCURL_LIBS="-L/usr/local/lib -lcurl -L/usr/kerberos/lib64" export LIBCURL_CFLAGS="-I/usr/local/include" but configure didn't care about it am I doing something wrong here? tnx Shahar Klein

[libvirt] How to get access to QEMU monitor?
by Jun Koi 26 Jul '09

26 Jul '09

Hi, I am running QEMU via libvirt (using virsh & virt-manager). Now I want to get access to the monitor interface of QEMU, so I can issue some commands to monitor. Is there anyway to do that? Thanks, J

[libvirt] VMware ESX driver progress
by Matthias Bolte 25 Jul '09

25 Jul '09

Hi, the development was hindered by our testing cluster being offline since 2 weeks due to server room cooling system maintenance. But I finally got a basic version of dump-XML done, that fills all fields of the virDomainDef that the VMX file contains data for. Changes since first announcement: - Move code into esx subdirectory - Add esxNodeGetInfo() - Fix esxDomainGetInfo() to report the correct value for memory - Add memory and max-memory getter/setters - Add CPU scheduler getter/setters - Validate a migration before trying to perform it - Replace esxUtil_Strdup() with strdup() and remove esxUtil_MigrateStringFromLibXML() - Add esxVI_EnsureSession() to handle expiring sessions - Separate VI client code into multiple files and generate most of the type handling code with macros - Add esxDomainDumpXML() based on esxVMX_ParseConfig() The ESX driver isn't complete yet, currently it supports: - domain lookup by ID, UUID and name - domain listing - domain info retrieval - domain suspend and resume - domain start and destroy - domain reboot and shutdown, if the VMware tools are installed inside the domain - domain migration with previous validation - domain memory configuration - domain CPU amount and scheduler configuration - domain XML-dump - domain XML-from-native (VMX) - node info retrieval - node hostname retrieval The next milestone is creating/defining a new domain from a domain XML config, but this will not be finished until feature freeze for 0.7.0 on friday.
