Hi, I'm trying to manage LXC instances through OpenStack, which use libvirt as a virtualization driver layer. After launching LXC instance, I simply could not attach to the console. virsh # list Id Name State ---------------------------------- 14366 instance-00000078 running virsh # console 14366 Connected to domain instance-00000078 Escape character is ^] And it keeps

'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present. This will prevent starting arrays in degraded state. Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state. Two new tests are added. This fixes rhbz1527852. Here is boot-benchmark

With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml instance-name ...

Hi, this series cleans up the Python sources, either static or generated, including also tests, to make them PEP 8 compliant; see https://www.python.org/dev/peps/pep-0008/ and tools like pep8. Almost all the issues reported by pep8 are fixed, reducing the issues from 3818 to 7. The changes should have no effect on the actual code, while it will help Python users with consistency with other

I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. Partitioning is lvm over raid. If i am using "logvol --grow i get "ValueError: not enough free space in volume group" Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. (10 extents or 320Mb per created logical volume) Following snippet is failing with

I tried using Javascript (gjs) with GObject-Introspection and did a port of the create_disk example which is attached below. Quite a bit of time was spent looking up stuff in the GLib reference and guessing how certain idioms translate to gjs. I used the traditional add_drive_opts method since I haven't been able to find how to specify the optional arguments to add_drive_opts. How does that

I am not sure if it''s a xen bug or lvm bug, or just my bad hardware, but here''s how to reproduce: /dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size. #lvcreate -L8192M -s -n snap1 vg0 #mount /dev/vg0/snap1 /mnt do some copying files here #umount /mnt #lvremove /dev/vg0/snap1 not removed! it says can''t allocated memory #xm mem-set 0 512 #lvremove

Hi all, We have a HP-UX 11i server running as a samba server. Users use Windows 2000 boxes with Service Pack 4 to connect to the samba server. Several days ago, we upgraded samba server from 2.0.7 to 3.0.5, and we started to experience the following problem: The general connection and access to the samba server is ok. However, under the samba share there have been some directories mounted from

I thought I'd test replacing a failed drive in a 4 drive raid 10 array on a CentOS 5.2 box before it goes online and before a drive really fails. I 'mdadm failed, removed', powered off, replaced drive, partitioned with sfdisk -d /dev/sda | sfdisk /dev/sdb, and finally 'mdadm add'ed'. Everything seems fine until I try to create a snapshot lv. (Creating a snapshot lv

Hi, how can I install a openSuSE 10.3 PV-guest on a LVM-drive of a openSuSE 10.3 host with Xen 3.10? On 10.2 with Xen 3.0.3 the openSuSE-YaST-module for managing VMs could install the system also on block-devices, unfortunately this is not possible anymore with OSS 10.3 :-( What I have tried: - I created two LVM-partitions, one for "/" one for swap. - Installing an OSS 10.2 PV-guest
