[libvirt] [RFC] New libvirt API for domain memory statistics reporting
by Adam Litke 10 Dec '09

10 Dec '09

When using ballooning to manage overcommitted memory on a host, a system for guests to communicate their memory usage to the host can provide information that will minimize the impact of ballooning on the guests while maximizing efficient use of host memory. The design of such a communication channel was recently added to version 0.8.2 of the VirtIO Spec (See Appendix G): - http://ozlabs.org/~rusty/virtio-spec/virtio-spec-0.8.2.pdf Host-side and guest-side implementations have been accepted for inclusion in their respective projects: - Guest: http://lkml.org/lkml/2009/11/30/274 - Host: http://lists.gnu.org/archive/html/qemu-devel/2009-12/msg00380.html The following patch series implements a new libvirt interface to expose these memory statistics. Thank you for your review and comments. [PATCH 1/6] domMemStats: Add domainMemStats method to struct _virDriver [PATCH 2/6] domMemStats: Add public symbol to libvirt API [PATCH 3/6] qemu-driver: Enable domainMemStats in the qemu driver [PATCH 4/6] remote-driver: Add domainMemStats support [PATCH 5/6] virsh: Enable virDomainMemStats as a new command [PATCH 6/6] python: Add python bindings for virDomainMemStats

[libvirt] Apologies for miss-configured Out-of-Office auto-replies
by Konrad Eriksson1 10 Dec '09

10 Dec '09

Dear list members, I'm terribly sorry for my badly configured Out-of-Office auto-reply feature in my email client that might have caused several replies to libvir-list emails received by me. It should be solved now (thanks to Daniel Veillard for pointing it out). Again sorry for the unintentional spaming. Happy virtualization! Regards, Konrad Eriksson

[libvirt] libvirk KVM save (migrate) terribly slow
by Nikola Ciprich 10 Dec '09

10 Dec '09

Hi, I noticed that using libvirt to save running domain is terribly slow, I mean it can take even 10 minutes to save VM with 2GB RAM, although the host is almost idle (8CPU, 16GB RAM). If I understand correctly, libvirt first pauses the vm and then migrates it to file (optionally through gzip). Restoring it back to running state is almost instant. I guess this is not what should be expected, is there something particular I should check? Thanks a lot in advance with best regards nik -- ------------------------------------- Nikola CIPRICH LinuxBox.cz, s.r.o. 28. rijna 168, 709 01 Ostrava tel.: +420 596 603 142 fax: +420 596 621 273 mobil: +420 777 093 799 www.linuxbox.cz mobil servis: +420 737 238 656 email servis: servis(a)linuxbox.cz -------------------------------------

[libvirt] [PATCH 1/5] reload iptables rules simply by re-adding them
by Mark McLoughlin 10 Dec '09

10 Dec '09

Currently, when we add iptables rules, we keep them on a list so that we can easily reload them on e.g. 'service libvirtd reload'. However, we don't save this list to disk, so if libvirtd is restarted we lose the ability to reload the rules. The fix is simple - just re-add the damn things on reload. Note, we delete the rules before re-adding them, just like the current behaviour of iptRulesReload(). * src/network/bridge_driver.c: re-add the iptables rules on reload. --- src/network/bridge_driver.c | 30 ++++++++++++++++++++++++------ 1 files changed, 24 insertions(+), 6 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 0342aa0..766f8cd 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -96,6 +96,8 @@ static int networkShutdownNetworkDaemon(virConnectPtr conn, struct network_driver *driver, virNetworkObjPtr network); +static void networkReloadIptablesRules(struct network_driver *driver); + static struct network_driver *driverState = NULL; @@ -291,12 +293,7 @@ networkReload(void) { &driverState->networks, driverState->networkConfigDir, driverState->networkAutostartDir); - - if (driverState->iptables) { - VIR_INFO0(_("Reloading iptables rules\n")); - iptablesReloadRules(driverState->iptables); - } - + networkReloadIptablesRules(driverState); networkAutostartConfigs(driverState); networkDriverUnlock(driverState); return 0; @@ -812,6 +809,27 @@ networkRemoveIptablesRules(struct network_driver *driver, iptablesSaveRules(driver->iptables); } +static void +networkReloadIptablesRules(struct network_driver *driver) +{ + unsigned int i; + + VIR_INFO0(_("Reloading iptables rules")); + + for (i = 0 ; i < driver->networks.count ; i++) { + virNetworkObjLock(driver->networks.objs[i]); + + if (virNetworkObjIsActive(driver->networks.objs[i])) { + networkRemoveIptablesRules(driver, driver->networks.objs[i]); + if (!networkAddIptablesRules(NULL, driver, driver->networks.objs[i])) { + /* failed to add but already logged */ + } + } + + virNetworkObjUnlock(driver->networks.objs[i]); + } +} + /* Enable IP Forwarding.

[libvirt] fc12 virsh tap device problem
by Chiradeep Vittal 10 Dec '09

10 Dec '09

Hi, On a fresh FC12 system, I am able to create and run KVM-based vms with tap networking using the qemu-kvm command line but not using virsh. I have user and group set to "root" in /etc/libvirt/qemu.conf. "user mode networking" works with virsh, but not tap!

[libvirt] qemu smbios options in domain xml format
by Phillip Balli 10 Dec '09

10 Dec '09

Hello, I could not find any explicit mention of support for the -smbios options which are present in qemu 0.10.5+ in the domain xml format or the qemu/kvm hypervisor driver pages. Is there some way to specify commands and options which are not described in the xml config by adjusting something in the way libvirt processes the xml? Or is providing smbios options just not supported currently?

I'd recommend giving virt-manager > 0.8.1 a shot, and report back here if you still hit virt-manager errors. > I installed the virt-manager-0.8.1 and virtinst-0.500.1. And the error was fixed. The virt-manager gui can works. Thank you! At the same time, i still can't create vm with the virt-manager-0.8.1 the error as below: Unable to complete install 'libvirt.libvirtError internal error Domain as didn't show up Traceback (most recent call last): File "/usr/local/dvirt/share/virt-manager/virtManager/create.py", line 1429, in do_install dom = guest.start_install(False, meter = meter) File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 660, in start_install return self._do_install(consolecb, meter, removeOld, wait) File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 758, in _do_install self.domain = self.conn.createLinux(install_xml, 0) File "/usr/lib/python2.4/site-packages/libvirt.py", line 974, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: internal error Domain as didn't show up And the reason is as Daniel P. Berrange said, "'ia64' is not listed as a valid architecture in qemu_conf.c, RHEL-5 KVM only supports x86_64". In other words, the libvirt didn't support KVM emulator running on ia64 architecture. Thank you for your work on virt-manager. -dustin _________________________________________________________________ Keep your friends updated―even when you’re not signed in. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/so…
