[Libvir] Accessing qemu from windows
by Gabriel Kaufmann 11 Mar '08

11 Mar '08

Hi, I'm running virsh from linux machine with the URI qemu+tcp://<user>:<password>@<ip>/system >From a linux machine (not the same that runs the libvirtd deamon) with libvirt 0.3.0, this URI allows me to connect. In the other hand, using the Virsh.exe (that comes with ocaml-libvirt-0.4.0.1.exe<http://libvirt.org/sources/ocaml/ocaml-libvirt-0.4.0.1.exe> ) on Windows XP, I receive the error 'Virtualization error: libvirt: VIR_ERROR_NO_CONNECT: VIR_FROM_NONE: could not connect to qemu:///system?' Is it a known bug, or is it configuration problem on my server?

[Libvir] PATCH: Don't make connection read-only when non-root
by Daniel P. Berrange 11 Mar '08

11 Mar '08

The virsh commands has long forced the connection to be read-only if running as non-root. This is bogus because it is perfectly capable of authenticating full read-write connections as non-root since we gained kerberos/policykit support. The user can always use the explicit --readonly flag if they only want a read only connection Dan.

[Libvir] PATCH: Fix libvirtd to not shutdown at startup
by Daniel P. Berrange 11 Mar '08

11 Mar '08

Changes to the daemon to make it called qemudShutdown() broke the network driver when run in --daemon mode. This is because the main daemon forks into the background, and the original PID then exits destroying any active networks & removing the iptables rules. # /usr/sbin/libvirtd --daemon Shutting down network 'default'iptables: No chain/target/match by that name iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: No chain/target/match by that name iptables: No chain/target/match by that name iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) iptables: Bad rule (does a matching rule exist in that chain?) Failed to bring down bridge 'virbr0' : No such device Failed to delete bridge 'virbr0' : No such device or address The core issue is that when forking into daemon mode the original process should immediately exit & not do invoke cleanup functions.

[Libvir] virsh start problem + patch
by Toth Istvan 11 Mar '08

11 Mar '08

Hello! I've been trying to use virsh to manage my Xen domains on Fedora 8. I found that I am unable to start any xen managed domains from virsh, because virsh complains that 'Domain is already running'. Actually, I am able to start them once, but once they are stopped, they are impossible to re-start. steps to reprouce: 1. use virt-install to install HVM domain 2. virsh start domain 3. shut down the domain from within the guest (i.e. Start-> shutdown) 4. virsh start domain -> error The problem appears with stock F8 (with current updates), but I've also tried the same with libvirt 4.1, with the same results. I've looked into the virsh code, and it seems that it was written with only only old-style xen in mind, and xen 3.1's managed domains break the logic. I've attached a simple patch against 0.4.1 that checks the actual domain state, instead of simply checking if libvirt knows about the domain. I have experienced a similar problem with virt-manager 0.5.3, where virt-manager is stuck showing 'running' status even after a domain has been shut down, hence it is not able to start the domain. regards István Tóth

[Libvir] PATCH: Remove use of polkit-grant
by Daniel P. Berrange 10 Mar '08

10 Mar '08

I formerly added support for calling polkit-auth and/or polkit-grant to get PolicyKit credentials. It turns out that polkit-grant is fundamentally flawed & unusable, so this patch removes use of polkit-grant. This is not a big issue, since polkit-auth is more functional and present in 0.7 or later. Second, it removes use of virRun() and does a direct execve() since we need to keep stdin & stdout open in all circumstances so the polkit-auth can prompt for & accept passwords depending on config.

[Libvir] PATCH: Allow Xen HVM kernel+initrd booting
by Daniel P. Berrange 10 Mar '08

10 Mar '08

The latest xen-unstable tree has support for booting HVM guests using an explicit kernel+initrd+cmdline, as an alternative to the traditional BIOS boot from harddisk/cdrom/network. This gives Xen HVM parity with KVM in terms of boot methods. The current libvirt Xen driver though assumes that Xen paravirt is always kernel+initrd or bootloader based, while Xen HVM is always BIOS based. This patch re-factors the Xen driver so that it allows kernel+initrd for both Xen paravirt and HVM guests. NB, Xen HVM previously abused the 'kernel' parameter in the SEXPR to refer to the HVM guest firmware (ie /usr/lib/xen/boot/hvmloader). With the new support for booting kernel+initrd in HVM guests, the firmware can now be specified using an explicit 'loader' parameter - for backwards compatability you can still use the old 'kernel' parameter too if doing a BIOS boot. Second, it is also now possible for a paravirt guest to provide an explicit patch to a QEMU device model, aka the <emulator> tag in libvirt, so this pach also enables that functionality for paravirt guests. Finally, since the paravirt framebuffer is tied up in all this code too, I also include John's patch to make us deal with <graphics> properly in legacy guests and old XenD. Thankfully we have a large test suite of SEXPR/XML files, so while this is a pretty major refactoring of code, I'm fairly confident we won't cause bad regressions. A couple of the existing test cases needed their sample SEXPR tweaked since we now generate a couple of (...) bits in a different order, the result is functionally the same though. Finally as an example, we can create a HVM guest on xen-unstable using this XML snippet - note how we can now pass parameters to the installer for HVM too ! <domain type='xen'> <name>kernel</name> <uuid>06ed00fe-1162-4fc4-b5d8-11993ee4a8b9</uuid> <os> <type>hvm</type> <loader>/usr/lib/xen/boot/hvmloader</loader> <kernel>/root/vmlinuz.f864</kernel> <initrd>/root/initrd.img.f864</initrd> <cmdline>console=ttyS0 console=tty0</cmdline> </os> <memory>540672</memory> <currentMemory>531456</currentMemory> <vcpu>1</vcpu> <on_poweroff>preserve</on_poweroff> <on_reboot>preserve</on_reboot> <on_crash>preserve</on_crash> <features> <acpi/> <apic/> <pae/> </features> <devices> <emulator>/usr/lib64/xen/bin/qemu-dm</emulator> <interface type='bridge'> <source bridge='xenbr0'/> <mac address='00:16:3e:0e:e8:b7'/> <script path='vif-bridge'/> </interface> <disk type='file' device='disk'> <driver name='file'/> <source file='/root/kernel.img'/> <target dev='hda'/> </disk> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' listen='0.0.0.0'/> <console tty='pty'/> </devices> </domain> src/xend_internal.c | 122 +++++++------ src/xml.c | 183 ++++++++------------ tests/sexpr2xmldata/sexpr2xml-fv-kernel.sexpr | 1 tests/sexpr2xmldata/sexpr2xml-fv-kernel.xml | 26 ++ tests/sexpr2xmldata/sexpr2xml-fv-legacy-vfb.sexpr | 70 +++++++ tests/sexpr2xmldata/sexpr2xml-fv-legacy-vfb.xml | 33 +++ tests/sexpr2xmltest.c | 20 ++ tests/xml2sexprdata/xml2sexpr-fv-kernel.sexpr | 1 tests/xml2sexprdata/xml2sexpr-fv-kernel.xml | 24 ++ tests/xml2sexprdata/xml2sexpr-fv-localtime.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv-usbmouse.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv-usbtablet.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv-utc.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv-v2.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv-vncunused.sexpr | 2 tests/xml2sexprdata/xml2sexpr-fv.sexpr | 2 tests/xml2sexprdata/xml2sexpr-no-source-cdrom.sexpr | 2 tests/xml2sexprtest.c | 11 + 18 files changed, 346 insertions(+), 161 deletions(-) Dan.

[Libvir] Not able to access the network.
by Spencer Parker 10 Mar '08

10 Mar '08

I have set up a machine using virsh, but I can't access it over the network. It has valid IP and everything like that. It is all running over eth1 and not eth0. Any idea as to why I can't get network access on it? I have assigned it a valid bridge. I try to ping the IP I gave it and I get nothing.
