[libvirt] Question about libvirt-qpid

by Atsushi SAKAI

2 questions. 1)Would you explain the use case for libvirt-qpid? Which case AMDQ messaging is good for. If I am missing some document, Please point me. By the way I am reading through following document. http://jira.amqp.org/confluence/download/attachments/2523279/amqp-model-d... I guess this is fit for huge data case? 2)Where is the document about set up libvirt-qpid? There is not in package document. Only in mailing list, it should goes some document. https://www.redhat.com/archives/libvir-list/2008-September/msg00388.html Thanks Atsushi SAKAI

[libvirt] [Patch][RFC] Fine grained access control in libvirt by rbac (0/3)

by Syunsuke HAYASHI

The series of patches introduces a fine grained access control to libvirt. They enable libvirt to enforce users what operations to invoke in role-based way. Our team found that Konrad and Daniel have similar interest to ours. Comments and suggestions are very welcome. Patches: - Embedding hooks in libvirt (1/3) - Access control library (2/3) - Example policy files (3/3)

[libvirt] PATCH: rpcgen portability fixes for remote_protocol.c/h

by Daniel P. Berrange

As per previous patches from John for Solaris, we ned a couple more fixes to the generated remote_protocol.c/h files for good portability. Specifically we need s/u_quad_t/uint64_t/g; s/quad_t/int64_t/g; s/xdr_u_quad_t/xdr_uint64_t/g; s/xdr_quad_t/xdr_int64_t/g; s/IXDR_GET_LONG/IXDR_GET_INT32/g; I have finally got around to verifying that this won't change wire ABI on Linux The first two data types int64 and quad_t are all fixed 64-bit ints, so that's safe. And the xdr_quad functions have this in the source strong_alias (xdr_int64_t, xdr_quad_t) strong_alias (xdr_int64_t, xdr_u_quad_t) So that change is no-op. Finally the glibc rpc/xdr.h has #define IXDR_GET_LONG(buf) ((long)IXDR_GET_U_INT32(buf)) So I believe this is all safe.

[libvirt] PATCH: Fix remote driver RPC recv handling

by Daniel P. Berrange

I noticed a odd error message randomly appearing from virsh after all commands had been run # virsh dominfo VirtTest Id: - Name: VirtTest UUID: 82038f2a-1344-aaf7-1a85-2a7250be2076 OS Type: hvm State: shut off CPU(s): 3 Max memory: 256000 kB Used memory: 256000 kB Autostart: disable libvir: Remote error : server closed connection It turns out that inthe for(;;) loop where I'm procesing incoming data, it was forgetting to break out of the loop when a completed RPC call had been received. Most of the time this wasn't problem, because there'd rarely be more data following, so it'd get EAGAIN next iteration & quit the loop. When shutting down though, you'd occassionally see the SIGHUP from read() before you get an EAGAIN, causing this error to be raised even though the RPC call had been successfully received. In addition, if there was a 2nd RPC reply already pending, we'd read and loose some of its data. Though I never saw this happen, it is a definite theoretical possibility, particularly over a TCP link with bad latency or fragementation or bursty traffic.

[libvirt] setting up dnsmasq options for PXE boot

by Dmitry Guryanov

Hello, I want to use PXE boot in kvm's virtual machines, but I've not found, how to configure libvirt for starting dhcp server with correct options for this. Now i have libvirt-0.5.1-2.fc10.x86_64 and virt-manager-0.6.0-5.fc10.x86_64, I've created VM using virt manager, with specifying PXE boot option. VM config contains following sections: <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='network'/> </os> ..... <interface type='network'> <mac address='54:52:00:0a:f6:00'/> <source network='nat_net'/> <model type='virtio'/> </interface> and config for virtual network nat_net: <network> <name>nat_net</name> <uuid>e02cfc6f-d7f8-6f81-8c19-bfa9d2a13a85</uuid> <forward dev='eth0' mode='nat'/> <bridge stp='on' forwardDelay='0' /> <ip address='192.168.107.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.107.128' end='192.168.107.254' /> </dhcp> </ip> </network> dnsmasq starts with following command line: /usr/sbin/dnsmasq --keep-in-foreground --strict-order --bind-interfaces--pid- file --conf-file --listen-address 192.168.107.1 --except-interface lo --dhcp- leasefile=/var/lib/libvirt/dhcp-nat_net.leases --dhcp-range 192.168.107.128,192.168.107.254 But for working PXE boot it should have also something like --dhcp-boot=pxelinux.0,itchy,192.168.107.1 So after starting VM it tries to boot from network, gets DHCP response and reports, that it doesn't contains filename option. So the question is - how to get it working correctly ? (If i start dnsmasq by hand with option --dhcp-boot=pxelinux.0,itchy,192.168.107.1 PXE boot works) -- Dmitry Guryanov

[libvirt] PATCH: Misc Xen driver bug fixes

by Daniel P. Berrange

Testing current CVS on RHEL-5 host exposed a number of problems in the Xen driver - When opening the remote driver for the network / storage / nodedev APIs, we had missed the initialization of several fields, resulting in a crash - Reporting of errors from the remote driver was leaking memory, due to missing xdr_free call. - Small possibility of de-referencing NULL when handling an error from the server, if no error message were provided - Mistakenly tries to activate Xen INotify driver when non-root, even though the directories it needs to monitor are chmod 0700 root.root - Gratuitous reporting of failure to connect to XenD's TCP port when running non-root, even though the proxy / remote driver will suceed - Bad return values from the xenDaemonOpen() method - Double free in the new xenStoreDoListDomains() method probably due to merge error The only really intreresting bit of the patch is for the first issue in the remote driver. I've basically pulled out alot of duplicated code into a couple of helper methods, so make these missing initialization less likely in future. remote_internal.c | 153 +++++++++++++++++++++++++----------------------------- xen_unified.c | 12 ++-- xend_internal.c | 50 ++++++----------- xs_internal.c | 2 4 files changed, 97 insertions(+), 120 deletions(-) Daniel Index: src/remote_internal.c =================================================================== RCS file: /data/cvs/libvirt/src/remote_internal.c,v retrieving revision 1.130 diff -u -p -u -p -r1.130 remote_internal.c --- src/remote_internal.c 28 Jan 2009 16:14:24 -0000 1.130 +++ src/remote_internal.c 28 Jan 2009 16:24:20 -0000 @@ -892,31 +892,70 @@ doRemoteOpen (virConnectPtr conn, goto cleanup;
