[libvirt] Some questions about the libvirt ESX driver
by Richard W.M. Jones 08 Jan '10

08 Jan '10

I'm playing with VMWare ESX 4.0 and I decided to try driving it from libvirt [git version]. Here are some random questions and issues I encountered, in no particular order. Listing domains works fine, but: (a) I have to specify ?no_verify=1 to get it to ignore the lack of valid https certificate. Is there some documentation on how to set up certificates correctly? [vSphere gives exactly the same error] (b) I have to type the root password (of the ESX server) each time. Can I avoid that? $ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' list --all Enter username for 192.168.2.121 [root]: Enter root password for 192.168.2.121: Id Name State ---------------------------------- - TestLinux shut off - TestWin shut off (c) Starting domains doesn't seem to work, and the error message is obscure: $ sudo ./tools/virsh -c 'esx://192.168.2.121/?no_verify=1' start TestLinux Enter username for 192.168.2.121 [root]: Enter root password for 192.168.2.121: error: Failed to start domain TestLinux error: internal error HTTP response code 500 for call to 'PowerOnVM_Task'. Fault: ServerFaultCode - The operation is not allowed in the current state. Is this to do with the "ask questions" API that was discussed on this list before? Specifying auto_answer=0 or auto_answer=1 didn't make any difference. (d) dumpxml XML output looks very good, and consistent with the other drivers. However it produces an odd <source file> attribute: <disk type='file' device='disk'> <driver name='lsilogic'/> <source file='[Storage1] TestLinux/TestLinux.vmdk'/> <target dev='sda' bus='scsi'/> </disk> <disk type='file' device='cdrom'> <source file='[Storage1] Fedora-12-x86_64-Live.iso'/> <target dev='hdc' bus='ide'/> </disk> (e) pool-list, net-list are not supported by the driver. That's a particular problem for me because I was really hoping to use the storage APIs from libvirt to access the VMDK files that contain domains (eg. [Storage1] TestLinux/TestLinux.vmdk in the example above). Is support for storage (particularly) and/or networks on the horizon for this driver?

[libvirt] RFC: Create a separate libvirt users mailing list ?
by Daniel P. Berrange 08 Jan '10

08 Jan '10

Hi Folks, We've been brainstorming ways to improve/broaden the libvirt community and one (of many) ideas is to create a separate libvirt users mailing list. The rationale is that this list is 95% patch submission from developers, often very high traffic and thus it may not be appealing for ordinary users to subscribe just to ask a question about libvirt usage. Although there is the virt-tools mailing list, that is really focused on the virt-manager family of apps, not a general purpose libvirt users community. Thus we're considering creating a new list libvirt-users(a)redhat.com To serve as a home for discussions relating to - Administrators/users of libvirt / libvirtd / virsh - Developers building applications on top of libvirt - Anyone else wishing to ask/talk about libvirt architecture / concepts / etc in real world deployment While the current list libvir-list(a)redhat.com To serve as continued home for most current traffic, specifically - Development of libvirt itself (libvirtd, hypervisor drivers, etc) - Development of libvirt language bindings (perl, python, java, etc) - Patch submission for libvirt & language bindings Essentially all libvirt code patches would be on libvir-list, while libvirt-users would be for app developer / end user admin discussions. For this to work of course, a significant number developers of libvirt currently on this list would also have to join libvirt-users, so we have people on the new list who are able to answer questions :-) Before we create a new list we'd like to hear from people on this list as to wether they think this would be beneficial. In particular we'd like your opinion if you are someone who's likely to switch to be exclusively on the libvirt-users list.

When you use virt-manager it has libvirtd fork/exec qemu-kvm. libvirtd will drop privileges and run qemu-kvm as user qemu (or perhaps root if you've edited qemu.conf). Regardless of the user, it clears capabilities. Reading PCI config space beyond just the header requires CAP_SYS_ADMIN. The above is reading the first 4 bytes of device dependent config space, and the kernel is returning 0 because qemu doesn't have CAP_SYS_ADMIN. Basically, this means that device assignment w/ libvirt will break MSI/MSI-X because qemu will never be able to see that the host device has those PCI capabilities. This, in turn, renders VF device assignment useless (since a VF is required to support MSI and/or MSI-X). Granting CAP_SYS_ADMIN for each qemu instance that does device assignment would render the privilege reduction useless (CAP_SYS_ADMIN is the kitchen sink catchall of the Linux capability system). Hmmph...

[libvirt] DNAT, bridge, iptables and network
by Mihamina Rakotomandimby 08 Jan '10

08 Jan '10

Manao ahoana, Hello, Bonjour, My server has 3 public IPs: IP1, IP2, IP3. I intend to create 3 bridges: virbr1, virbr2, virbr3. Each bridge will NAT from 3 to 5 KVM guests. About IP1: I would like incoming connexion on IP1 to: - IP1:80 to be DNAT'd to one virbr1 VM, specialized on HTTP - IP1:3306 to be DNAT'd to another virbr1 VM, specialized on MySQL - IP1:53 to be DNAT'd to another virbr1 VM, specialized on DNS Same about IP2 and IP3. Should I assign a public IP address to each brdige? I think "no" because there will be a problem of network segment: --> What range will I give to the guests? I think my only solution is to give private IPs (192.168.X.X) to the brigdes (3 separate subnets), and use iptables with something like: iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 80 \ -j DNAT --to-destination $VIRBR1_HTTP_GUEST iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 3306 \ -j DNAT --to-destination $VIRBR1_MySQL_GUEST iptables -t nat -A PREROUTING -p udp -d $IP1 --dport 53 \ -j DNAT --to-destination $VIRBR1_DNS_GUEST Should be alright?

[libvirt] [Patch v0.5] iSCSI Multi-IQN (Libvirt Support)
by Shyam Iyer 08 Jan '10

08 Jan '10

This patch set realizes the multi-IQN concept discussed in an earlier thread http://www.mail-archive.com/libvir-list@redhat.com/msg16706.html And here .. http://www.mail-archive.com/libvir-list@redhat.com/msg17499.html The patch realizes an XML schema like the one below and allows libvirt to read through it to create storage pools. These XMLs when created using a virtualization manager realize unique VM to storage LUN mappings through a single console and thus opening up possibilities for the following scenarios - * possibility of multiple IQNs for a single Guest * option for hypervisor's initiator to use these IQNs on behalf of the guest Change Log from v0.4: 1) Set default tab space to 4(Hopefully this is corrected this time ;) ) 2) Review comments from Dave Allan a) Use output of "iscsiadm -m iface" to search for existing iqn names in the iface files. 3) Create new unique iface file names for user provided iqn names if the iqns are not present in the existing iface files. Change Log from v0.3: 1) Set default tab space to 4 2) Use Case Description for Commit Log 3) Review comments from Dave Allan a) No initiator iqn in the xml would mean use of the default initiator iqn name b) Initiator iqn provided would mean a unique session to be created using the provided iqn name. c) Single iSCSI session per pool 4) Added syntax in doc/schemas/storagepool.rng There are no new errors introduced by this patch with "make check" and "make syntax-check" tests.

by Jim Fehlig 07 Jan '10

07 Jan '10

xen-unstable c/s 20685 changed the domctl interface, adding a field to xen_domctl_getdomaininfo structure. This additional field causes stack corruption in libvirt. xen-unstable c/s 20711 rightly bumped the domctl interface version so it is at least possible to handle the new field. The attached patch accounts for shr_pages field added to xen_domctl_getdomaininfo structure. I'm not thrilled about the changes to all the macros - suggestions for improvement welcomed. Tested with domctl version 5 and 6. Regards, Jim

[libvirt] libvirt 0.7.5 vs qemu 0.12.1 imcompatability?
by Tom Hughes 07 Jan '10

07 Jan '10

The update from qemu 0.11.0 to qemu 0.12.1 in the virt-preview repository seems to have broken things. Starting a VM now just gives me a blank screen and a log which says: Option 'ipv4': Use 'on' or 'off' Failed to parse "yes" for "dummy.ipv4" I assume libvirt is sending a it a command on the monitor interface that it no longer understands...

[libvirt] [PATCH] xend_internal: don't let invalid input provoke NULL dereference
by Jim Meyering 06 Jan '10

If there's a good reason to test for NULL "conn", then we certainly must not dereference "conn" before that point. This assumes we do want to retain the NULL test. Note that many other functions perform this same test. >From 2c7b628728efcb5a59c1e7aa1cba763f5ef0045a Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 6 Jan 2010 12:59:21 +0100 Subject: [PATCH] xend_internal: don't let invalid input provoke NULL dereference * src/xen/xend_internal.c (xenDaemonOpen_unix): Do not dereference a NULL "conn".

[libvirt] [PATCH] esx: Fix 'vpx' MAC address range and allow arbitrary MAC addresses
by Matthias Bolte 06 Jan '10

06 Jan '10

The MAC addresses with 00:50:56 prefix are split into several ranges: 00:50:56:00:00:00 - 00:50:56:3f:ff:ff 'static' range (manually assigned) 00:50:56:80:00:00 - 00:50:56:bf:ff:ff 'vpx' range (assigned by a VI Client) Erroneously the 'vpx' range was assumed to be larger and to occupy the remaining addresses of the 00:50:56 prefix that are not part of the 'static' range. 00:50:56 was used as prefix for generated MAC addresses, this is not possible anymore, because there are gaps in the allowed ranges. Therefore, change the prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway. Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option to false in case the MAC address doesn't fall into any predefined range. * docs/drvesx.html.in: update website accordingly * src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29 * src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC addresses * tests/vmx2xml*, tests/xml2vmx*: add some basic MAC address range tests --- docs/drvesx.html.in | 74 ++++++++++++++++++++-- src/esx/esx_driver.c | 2 +- src/esx/esx_vmx.c | 49 +++++++++------ tests/vmx2xmldata/vmx2xml-ethernet-generated.vmx | 8 +++ tests/vmx2xmldata/vmx2xml-ethernet-generated.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-other.vmx | 8 +++ tests/vmx2xmldata/vmx2xml-ethernet-other.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-static.vmx | 7 ++ tests/vmx2xmldata/vmx2xml-ethernet-static.xml | 19 ++++++ tests/vmx2xmldata/vmx2xml-ethernet-vpx.vmx | 7 ++ tests/vmx2xmldata/vmx2xml-ethernet-vpx.xml | 19 ++++++ tests/vmx2xmltest.c | 5 ++ tests/xml2vmxdata/xml2vmx-ethernet-generated.vmx | 13 ++++ tests/xml2vmxdata/xml2vmx-ethernet-generated.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-other.vmx | 13 ++++ tests/xml2vmxdata/xml2vmx-ethernet-other.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-static.vmx | 12 ++++ tests/xml2vmxdata/xml2vmx-ethernet-static.xml | 14 ++++ tests/xml2vmxdata/xml2vmx-ethernet-vpx.vmx | 12 ++++ tests/xml2vmxdata/xml2vmx-ethernet-vpx.xml | 14 ++++ tests/xml2vmxtest.c | 5 ++ 21 files changed, 320 insertions(+), 27 deletions(-) create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-generated.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-generated.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-other.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-other.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-static.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-static.xml create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-vpx.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-ethernet-vpx.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-generated.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-generated.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-other.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-other.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-static.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-static.xml create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-vpx.vmx create mode 100644 tests/xml2vmxdata/xml2vmx-ethernet-vpx.xml diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index b7909ff..44a144f 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -16,8 +16,8 @@ SOAP based <a href="http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide/"> VMware Virtual Infrastructure API</a> (VI API) to communicate with the - ESX server, like the VMware Virtual Infrastructure Client does.
