[libvirt] [PATCH] bridge: add the firewalld zone support
by Federico Simoncelli 11 Apr '13

11 Apr '13

This patch adds the support for the firewalld zones in the virtual bridges managed by libvirt allowing to configure the rules as for all the other interfaces. After assigning a fwzone to the bridge it is then possible to configure the firewall rules through the firwalld daemon, e.g. enabling or disabling connections to certain services located on the host. The firewalld events (e.g. restart, reload) are managed with the preexisting infrastructure that is already in place to reinstate the general iptables rules.

[libvirt] [PATCH v3 1/3] Add NVRAM device

[libvirt] [PATCH v3] qemu: Set correct migrate host in client_migrate_info
by Michal Privoznik 11 Apr '13

11 Apr '13

https://bugzilla.redhat.com/show_bug.cgi?id=920441 Currently, we are discarding listen attribute from qemu cookie even though we strive to gather it. This result in not so cool bug: if user have different networks, one for management/migration, and one for VNC/SPICE we pass incorrect host to the qemu in client_migrate_info. What we actually pass is remote hostname, while we should be passing remote listen address. It doesn't matter as long as these two are the same, but they don't need necessary to be like that. --- src/conf/domain_conf.c | 4 +++- src/qemu/qemu_migration.c | 8 +++++++- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 68f024f..6757738 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -16557,8 +16557,10 @@ virDomainGraphicsListenGetAddress(virDomainGraphicsDefPtr def, size_t ii) virDomainGraphicsListenDefPtr listenInfo = virDomainGraphicsGetListen(def, ii, false); + /* even a network can have a listen address */ if (!listenInfo || - (listenInfo->type != VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_ADDRESS)) + !(listenInfo->type == VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_ADDRESS || + listenInfo->type == VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_NETWORK)) return NULL; return listenInfo->address; } diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index 41ad768..a263668 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1720,6 +1720,7 @@ qemuDomainMigrateGraphicsRelocate(virQEMUDriverPtr driver, { qemuDomainObjPrivatePtr priv = vm->privateData; int ret; + char *listenAddress = cookie->graphics->listen; if (!cookie) return 0; @@ -1733,12 +1734,17 @@ qemuDomainMigrateGraphicsRelocate(virQEMUDriverPtr driver, if (cookie->graphics->type != VIR_DOMAIN_GRAPHICS_TYPE_SPICE) return 0; + if (!listenAddress || + STREQ(listenAddress, "0.0.0.0") || + STREQ(listenAddress, "::")) + listenAddress = cookie->remoteHostname; + ret = qemuDomainObjEnterMonitorAsync(driver, vm, QEMU_ASYNC_JOB_MIGRATION_OUT); if (ret == 0) { ret = qemuMonitorGraphicsRelocate(priv->mon, cookie->graphics->type, - cookie->remoteHostname, + listenAddress, cookie->graphics->port, cookie->graphics->tlsPort, cookie->graphics->tlsSubject); -- 1.8.1.5
