Hi, I resolved it by adding or uncommenting "/dev/vfio/vfio" in cgroup_device_acl list in /etc/libvirtd/qemu.conf file and restart libvird service .
Now when I listed nova instances am not getting any Network shown [stack@Controller images]$ nova list +--------------------------------------+----------+--------+------------+-------------+----------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+----------+--------+------------+-------------+----------+ | 6cd81ab3-d60f-4511-ad5d-7d337af3cacd | ubuntuvm | ACTIVE | - | Running | | +--------------------------------------+----------+--------+------------+-------------+----------+ [stack@Controller images]$ -----Original Message----- From: Steve Gordon [mailto:sgor...@redhat.com] Sent: Tuesday, May 26, 2015 9:45 PM To: Moshe Levi Cc: Kamsali, RaghavendraChari [ENGINEERING/IN]; OpenStack Development Mailing List (not for usage questions); openstack@lists.openstack.org Subject: Re: [Openstack] [openstack-dev] PCI pass-through SRIOV ----- Original Message ----- > From: "Moshe Levi" <mosh...@mellanox.com> > To: "RaghavendraChari Kamsali (Artesyn)" > <raghavendrachari.kams...@artesyn.com>, "OpenStack Development Mailing > List > > This is a different error > > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] if ret == -1: raise libvirtError > ('virDomainCreateWithFlags() failed', dom=self) > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] libvirtError: internal error: > process exited while connecting to monitor: 2015-05-26T04:34:07.980897Z > qemu-kvm: > -device vfio-pci,host=81:02.3,id=hostdev0,bus=pci.0,addr=0x4: vfio: > failed to open /dev/vfio/vfio: Operation not permitted > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] 2015-05-26T04:34:07.980951Z qemu-kvm: > -device vfio-pci,host=81:02.3,id=hostdev0,bus=pci.0,addr=0x4: vfio: > failed to setup container for group 49 > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] 2015-05-26T04:34:07.980970Z qemu-kvm: > -device vfio-pci,host=81:02.3,id=hostdev0,bus=pci.0,addr=0x4: vfio: > failed to get group 49 > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] 2015-05-26T04:34:07.980995Z qemu-kvm: > -device vfio-pci,host=81:02.3,id=hostdev0,bus=pci.0,addr=0x4: Device > initialization failed. > 2015-05-26 13:34:08.081 TRACE nova.compute.manager [instance: > 101776a0-cd2e-47b9-bdc4-1097782201c6] 2015-05-26T04:34:07.981019Z qemu-kvm: > -device vfio-pci,host=81:02.3,id=hostdev0,bus=pci.0,addr=0x4: Device > 'vfio-pci' could not be initialized > > You are using intel card therefore I think you should contact them and > ask if this card is supported. In addition there are a number of Intel cards for which ACS quirks had to be added to the kernel, this was done fairly recently in patches like this one: http://www.spinics.net/lists/kernel/msg1951202.html You may want to check whether a) your card is one of those impacted and b) your kernel has these patches, though your output does not appear to be an exact match for what we were seeing in https://bugzilla.redhat.com/show_bug.cgi?id=1141399 Thanks, -- Steve Gordon, RHCE Sr. Technical Product Manager, Red Hat Enterprise Linux OpenStack Platform _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
