[libvirt] [PATCH v2] nwfilter: enable hex number inputs in filter XML
by Stefan Berger 26 Apr '10

26 Apr '10

With this patch I want to enable hex number inputs in the filter XML. A number that was entered as hex is also printed as hex unless a string representing the meaning can be found. I am also extending the schema and adding a test case. A problem with the DSCP value is fixed on the way as well. Changes from V1 to V2: - using asHex boolean in all printf type of functions to select the output format in hex or decimal format Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com> --- docs/schemas/nwfilter.rng | 20 ++++ src/conf/nwfilter_conf.c | 121 +++++++++++++++++------------ src/conf/nwfilter_conf.h | 18 ++-- src/nwfilter/nwfilter_ebiptables_driver.c | 2 tests/nwfilterxml2xmlin/hex-data-test.xml | 56 +++++++++++++ tests/nwfilterxml2xmlout/hex-data-test.xml | 21 +++++ tests/nwfilterxml2xmltest.c | 2 7 files changed, 184 insertions(+), 56 deletions(-) Index: libvirt-acl/src/conf/nwfilter_conf.h =================================================================== --- libvirt-acl.orig/src/conf/nwfilter_conf.h +++ libvirt-acl/src/conf/nwfilter_conf.h @@ -65,15 +65,17 @@ enum virNWFilterEntryItemFlags { enum attrDatatype { DATATYPE_UINT16 = (1 << 0), DATATYPE_UINT8 = (1 << 1), - DATATYPE_MACADDR = (1 << 2), - DATATYPE_MACMASK = (1 << 3), - DATATYPE_IPADDR = (1 << 4), - DATATYPE_IPMASK = (1 << 5), - DATATYPE_STRING = (1 << 6), - DATATYPE_IPV6ADDR = (1 << 7), - DATATYPE_IPV6MASK = (1 << 8), + DATATYPE_UINT16_HEX = (1 << 2), + DATATYPE_UINT8_HEX = (1 << 3), + DATATYPE_MACADDR = (1 << 4), + DATATYPE_MACMASK = (1 << 5), + DATATYPE_IPADDR = (1 << 6), + DATATYPE_IPMASK = (1 << 7), + DATATYPE_STRING = (1 << 8), + DATATYPE_IPV6ADDR = (1 << 9), + DATATYPE_IPV6MASK = (1 << 10), - DATATYPE_LAST = (1 << 9), + DATATYPE_LAST = (1 << 11), }; Index: libvirt-acl/src/conf/nwfilter_conf.c =================================================================== --- libvirt-acl.orig/src/conf/nwfilter_conf.c +++ libvirt-acl/src/conf/nwfilter_conf.c @@ -430,7 +430,9 @@ checkMacProtocolID(enum attrDatatype dat if (datatype == DATATYPE_STRING) { if (intMapGetByString(macProtoMap, (char *)value, 1, &res) == 0) res = -1; - } else if (datatype == DATATYPE_UINT16) { + datatype = DATATYPE_UINT16; + } else if (datatype == DATATYPE_UINT16 || + datatype == DATATYPE_UINT16_HEX) { res = (uint32_t)*(uint16_t *)value; if (res < 0x600) res = -1; @@ -438,7 +440,7 @@ checkMacProtocolID(enum attrDatatype dat if (res != -1) { nwf->p.ethHdrFilter.dataProtocolID.u.u16 = res; - nwf->p.ethHdrFilter.dataProtocolID.datatype = DATATYPE_UINT16; + nwf->p.ethHdrFilter.dataProtocolID.datatype = datatype; return 1; } @@ -451,13 +453,17 @@ macProtocolIDFormatter(virBufferPtr buf, virNWFilterRuleDefPtr nwf) { const char *str = NULL; + bool asHex = true; if (intMapGetByInt(macProtoMap, nwf->p.ethHdrFilter.dataProtocolID.u.u16, &str)) { virBufferVSprintf(buf, "%s", str); } else { - virBufferVSprintf(buf, "%d", nwf->p.ethHdrFilter.dataProtocolID.u.u16); + if (nwf->p.ethHdrFilter.dataProtocolID.datatype == DATATYPE_UINT16) + asHex = false; + virBufferVSprintf(buf, asHex ?

[libvirt] [PATCH] nwfilter: enable hex number inputs in filter XML
by Stefan Berger 26 Apr '10

26 Apr '10

With this patch I want to enable hex number inputs in the filter XML. A number that was entered as hex is also printed as hex unless a string representing the meaning can be found. I am also extending the schema and adding a test case. A problem with the DSCP value is fixed on the way as well.

[libvirt] Q of Libvirt and Xen
by ��... ��... 26 Apr '10

26 Apr '10

Hi ! sir I'm newbie of xen and libvirt. I'm practice use libvirt API for control xen on CenOS 5.4 using C language. How can I learn it. I can't found a simple C file for testing libvirt and xen. please suggest me for How can I using libvirt for control xen with C and May I have a example code C for run testing a libvirt. Thinks.

[libvirt] Libvirt debug API
by Chris Lalancette 26 Apr '10

26 Apr '10

Hello, In response to a lot of the talk of qemud lately on qemu-devel, the libvirt community would like to put forward a proposal to help enable debug/advanced options when using various hypervisors. The goals of this API are: 1) To enable more rapid access to hypervisor features before proper libvirt API's are designed around them. 2) To facilitate debugging and access to advanced features that may not fit into the normal libvirt world-view. Caveats: 1) Unlike other libvirt API's, this one will explicitly *not* be guaranteed ABI/API compatible between libvirt updates. 2) Again unlike other libvirt API's, access and configuration of the debug section of a domain will be highly hypervisor dependent. 3) Application developers will be strongly discouraged from using this API because of the above 2 issues. To help in this, the API's will be in a separate library that developers will explicitly have to link to, and it will have a different (but largely compatible) wire protocol. 4) We don't expect this API to solve all of the issues brought up during the qemud discussion. Our initial goal is just to give ready access of the qemu command-line and monitor to developers. With that being said, our initial proposal follows. We expect this to evolve over time as we get more feedback, but we think this proposal addresses at least 2 of the major pain points qemu developers have while trying to use libvirt. The initial debug XML for qemu would be: <domain type='kvm'> <name>myguest</name> ... <debug> <monitorpassthrough/> <commandline> <extra>qemu arguments</extra> <alter option="optname"> <rename>newname</rename> <match>REGEXP</match> <modify>foo=on</modify> <extra>-bar</extra> </alter> </commandline> </debug> </domain> Raw access to the qemu monitor will be disabled by default; the <monitorpassthrough/> tag enables the ability to send QMP (or text, if you are using older qemu) messages straight through to the monitor. To do this there will be an additional API entry point named virDomainDebugCommand() which takes an arbitrary string and passes it to the monitor, and returns an arbitrary string as a result. Thus you could pass in either "info cpus" if using the text monitor or '{ "execute": "query-cpus" }' if using QMP. The <commandline><extra> tag does exactly what you might expect; appends the exact string to the qemu command-line. The <alter> tag gets more interesting. The idea is that <alter> would allow you to modify the libvirt-generated qemu command-line in arbitrary ways. How this would work is probably best explained with some examples: <commandline> <alter option="-net"> <rename>-netdev</rename> </alter> </commandline> In this example, all options named -net on the qemu command-line are renamed to -netdev. <commandline> <alter option="-net"> <extra>-usbtablet</extra> </alter> </commandline> In this example, if (and only if) a -net option is seen, then -usbtablet is appended to the qemu command-line. <commandline> <alter option="-net"> <match>$.*name=hostnet0.*$</match> <modify>\1,tap</modify> </alter> </commandline> This gets more complicated (but also more powerful). In this case, any -net option where the argument *also* matches the regex in <match> will be modified to append the ",tap" string. Think of it as a sed expression, s/match/modify/, against the argument to the -net option, and it makes more sense. We are hoping to refine this proposal based on feedback, so comments and criticisms are welcome! -- Chris Lalancette

[libvirt] [PATCH 0/1] port profile id
by David Allan 26 Apr '10

26 Apr '10

The following proof of concept patch attempts to show how we might support the use of port profile IDs. The ID would be associated with an interface on a VM and provided to the network infrastructure at VM start time. Since the interfaces by which the id can be provided are still in flux, the use function is only a stub.

[libvirt] virsh is not working for other than root users.
by Kumar L Srikanth-B22348 26 Apr '10

26 Apr '10

Hi, I am using libvirt 0.8.0 on Fedora 32 bit system. When I issue "virsh -c lxc:///" with root permissions I m able to see 'virsh' console. But, if I changed to other user say "su srikanth", and issue the same command, I am not able to see the virsh console. I am getting "authentication failed" error. Can anybody please help me in solving the issue? Regards, Srikanth.

[libvirt] Question on xm and virsh listing
by Nandini Chandra 24 Apr '10

24 Apr '10

I'd like to understand the exact mechanism for retrieving the list of guests by xm/xend and virsh/libvirt.In what situations could the output of 'xm list' differ from 'virsh list'?Which of these two is more accurate? I'd appreciate any pointers. Thanks.
