yes, the patch can work, when I execute virsh dump --reboot <domian> <file>
and the type of file is: QEMU's suspend to disk image
-------- ???? -------- ??: [libvirt] [PATCH] qemu: Allow domain reboot after core dump ??: Tue, 20 Sep 2011 13:34:27 +0200 ???: Michal Privoznik <mpriv...@redhat.com> ???: libvir-list@redhat.com This patch introduces possibility to reboot domain after core dump finishes. The new flag VIR_DUMP_REBOOT was added to virDomainCoreDumpFlags. The new functionality is accessible via virsh too: virsh dump --reboot<domain> --- include/libvirt/libvirt.h.in | 1 + src/qemu/qemu_driver.c | 8 +++++++- tools/virsh.c | 3 +++ 3 files changed, 11 insertions(+), 1 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 39155a6..8c41f5a 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -748,6 +748,7 @@ typedef enum { VIR_DUMP_CRASH = (1<< 0), /* crash after dump */ VIR_DUMP_LIVE = (1<< 1), /* live dump */ VIR_DUMP_BYPASS_CACHE = (1<< 2), /* avoid file system cache pollution */ + VIR_DUMP_REBOOT = (1<< 3), /* reboot domain after dump finishes */ } virDomainCoreDumpFlags; /* Domain migration flags. */ diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index e2f428f..22576a8 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3104,7 +3104,8 @@ static int qemudDomainCoreDump(virDomainPtr dom, int ret = -1; virDomainEventPtr event = NULL; - virCheckFlags(VIR_DUMP_LIVE | VIR_DUMP_CRASH | VIR_DUMP_BYPASS_CACHE, -1); + virCheckFlags(VIR_DUMP_LIVE | VIR_DUMP_CRASH | + VIR_DUMP_BYPASS_CACHE | VIR_DUMP_REBOOT, -1); qemuDriverLock(driver); vm = virDomainFindByUUID(&driver->domains, dom->uuid); @@ -3189,6 +3190,11 @@ cleanup: if (event) qemuDomainEventQueue(driver, event); qemuDriverUnlock(driver); + + if ((ret == 0)&& (flags& VIR_DUMP_REBOOT)) { + qemuDomainReboot(dom, 0); + } + return ret; } diff --git a/tools/virsh.c b/tools/virsh.c index d575425..74f6a79 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -2840,6 +2840,7 @@ static const vshCmdOptDef opts_dump[] = { {"crash", VSH_OT_BOOL, 0, N_("crash the domain after core dump")}, {"bypass-cache", VSH_OT_BOOL, 0, N_("avoid file system cache when saving")}, + {"reboot", VSH_OT_BOOL, 0, N_("reboot the domain after core dump")}, {"domain", VSH_OT_DATA, VSH_OFLAG_REQ, N_("domain name, id or uuid")}, {"file", VSH_OT_DATA, VSH_OFLAG_REQ, N_("where to dump the core")}, {NULL, 0, 0, NULL} @@ -2869,6 +2870,8 @@ cmdDump(vshControl *ctl, const vshCmd *cmd) flags |= VIR_DUMP_CRASH; if (vshCommandOptBool(cmd, "bypass-cache")) flags |= VIR_DUMP_BYPASS_CACHE; + if (vshCommandOptBool(cmd, "reboot")) + flags |= VIR_DUMP_REBOOT; if (virDomainCoreDump(dom, to, flags)< 0) { vshError(ctl, _("Failed to core dump domain %s to %s"), name, to); -- 1.7.3.4 -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
