[libvirt] Segmentation fault when shutting down VMs
by Thomas Treutner 11 Dec '09

11 Dec '09

Hi, I'm facing another problem with latest git. This happens regularly when shutting down VM(s): http://pastebin.com/m4ef1d93f It doesn't depend on which or how many VM is/are shut down, or if I have a VNC connection to a VM that is shutting down. Sometimes after a segv, I get this: http://pastebin.com/m5260bf21 It seems to me that libvirt tries to query a qemu monitor that is no longer alive? kr,tom

[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.
