Re: [libvirt] [PATCH 1/2] REPRODUCER -- DO NOT PUSH

https://bugzilla.redhat.com/show_bug.cgi?id=1553085 This breaks hotplug so that we can see whether the file was left dangling. Reproduce by: virsh create dom.xml virsh attach-device memplug mem.xml ls /var/lib/libvirt/qemu/ram/libvirt/qemu/*-memplug After the failed hotplug, qemu should leave behind the file called 'dimm0' in the above path. The original bugreport was caused by failing in the 'device-add' phase. --- dom.xml | 110 ++++++++++++++++++++++++++++++++++++++++++++++++ mem.xml | 6 +++ src/qemu/qemu_hotplug.c | 3 ++ 3 files changed, 119 insertions(+) create mode 100644 dom.xml create mode 100644 mem.xml diff --git a/dom.xml b/dom.xml new file mode 100644 index 0000000000..242615569e --- /dev/null +++ b/dom.xml @@ -0,0 +1,110 @@ +<domain type='kvm'> + <name>memplug</name> + <uuid>41277c77-9bb0-416c-aacc-4dcac4e03cea</uuid> + <maxMemory slots='16' unit='KiB'>152428800</maxMemory> + <memory unit='KiB'>1024000</memory> + <currentMemory unit='KiB'>1024000</currentMemory> + <memoryBacking> + <source type='file'/> + <access mode='shared'/> + <allocation mode='immediate'/> + </memoryBacking> + <vcpu placement='static' current='2'>8</vcpu> + <os> + <type arch='x86_64' machine='pc-i440fx-2.9'>hvm</type> + <bootmenu enable='yes'/> + </os> + <features> + <acpi/> + <apic/> + <vmport state='off'/> + </features> + <cpu> + <numa> + <cell id='0' cpus='0,2,4,6' memory='512000' unit='KiB'/> + <cell id='1' cpus='1,3,5,7' memory='512000' unit='KiB'/> + </numa> + </cpu> + <clock offset='utc'> + <timer name='rtc' tickpolicy='catchup'/> + <timer name='pit' tickpolicy='delay'/> + <timer name='hpet' present='no'/> + </clock> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>restart</on_crash> + <pm> + <suspend-to-mem enabled='no'/> + <suspend-to-disk enabled='no'/> + </pm> + <devices> + <emulator>/usr/bin/qemu-system-x86_64</emulator> + <controller type='usb' index='0' model='ich9-ehci1'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x7'/> + </controller> + <controller type='usb' index='0' model='ich9-uhci1'> + <master startport='0'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0' multifunction='on'/> + </controller> + <controller type='usb' index='0' model='ich9-uhci2'> + <master startport='2'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x1'/> + </controller> + <controller type='usb' index='0' model='ich9-uhci3'> + <master startport='4'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x2'/> + </controller> + <controller type='pci' index='0' model='pci-root'/> + <controller type='virtio-serial' index='0'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> + </controller> + <controller type='ide' index='0'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> + </controller> + <controller type='scsi' index='0' model='lsilogic'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> + </controller> + <serial type='pty'> + <target type='isa-serial' port='0'> + <model name='isa-serial'/> + </target> + </serial> + <console type='pty'> + <target type='serial' port='0'/> + </console> + <channel type='unix'> + <target type='virtio' name='org.qemu.guest_agent.0'/> + <address type='virtio-serial' controller='0' bus='0' port='1'/> + </channel> + <channel type='spicevmc'> + <target type='virtio' name='com.redhat.spice.0'/> + <address type='virtio-serial' controller='0' bus='0' port='2'/> + </channel> + <input type='tablet' bus='usb'> + <address type='usb' bus='0' port='1'/> + </input> + <input type='mouse' bus='ps2'/> + <input type='keyboard' bus='ps2'/> + <graphics type='spice' autoport='yes'> + <listen type='address'/> + <image compression='off'/> + </graphics> + <sound model='ich6'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> + </sound> + <video> + <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> + </video> + <redirdev bus='usb' type='spicevmc'> + <address type='usb' bus='0' port='2'/> + </redirdev> + <redirdev bus='usb' type='spicevmc'> + <address type='usb' bus='0' port='3'/> + </redirdev> + <memballoon model='virtio'> + <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> + </memballoon> + </devices> +</domain> +
